ERROR ENVVAR NOT FOUND error usually comes followed by The system could not find the environment option that was entered message.

This is a system error, and it can occur on any Windows operating system, including Windows 10. Since this error is somewhat common, we’re going to show you how to properly fix it.

How can I fix the System could not find the environment option?

1. Scan your PC for viruses

Another common cause for these types of problems is malware infection. Sometimes malware can make changes to your system and cause this and many other errors to appear.

If you suspect that your PC is infected by malware, we advise you to perform a full scan as soon as possible. But for that, you will need a powerful and reliable antivirus.

We recommend you get an antivirus with a high detection rate and run a full PC scan and remove any threats found.

Reliable antiviruses have powerful firewalls, a good privacy policy, as well as multiple layers of protection to ensure your PC is fully secure.

Of course, using great antivirus also protects you online by blocking any potentially dangerous websites.

2. Add the missing environment variable

  1. Click the Power button from the Start menu, and while holding the Shift key pressed, click the Restart option.
  2. Click on Troubleshoot, then on Advanced options, select Startup Settings and click the Restart button.
  3. Press the appropriate key to enter Safe Mode.
  4. Press Windows Key + S, enter advanced settings, and choose View advanced system settings from the results.
  5. System Properties window will now appear. Click on Environment Variables button.
  6. Go to System variables section and click on New.
  7. Enter windir as Variable name and C:Windows as Variable value. Click OK to save changes.
  8. After saving your changes, restart your PC and check if the problem is resolved.

Note: Windows uses environment variables to access certain files faster.

These variables are related to system directories, and if a certain variable is missing or not configured properly you can get The system could not find the environment option that was entered error message.

This issue can appear if %WINDIR% variable is missing.

Keep in mind that it’s not mandatory to perform this solution from Safe Mode so you’re free to try it without entering it.

This issue can occur due to other missing environment variables, so to find out which of them are missing, you should compare the list containing these options with another working PC.

Add the environment variable using the Registry Editor

  1. Press Windows Key + R, enter regedit and press Enter or click OK.
  2. In the left pane, navigate to: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerEnvironment
  3. If the windir value is missing, you need to recreate it. Right-click the empty space in the right pane and choose New, then select String Value.
  4. Enter windir as the name of the new string.
  5. Double click newly created windir string to open its properties. Enter C:Windows as Value data and click OK to save changes.
  6. Close the Registry Editor and restart your PC to apply the changes.

Note: This solution is provided if you can’t access Advanced System Settings. Modifying the registry can be potentially dangerous so we advise you to create a backup just in case.

If the windir value is present in your registry, it’s possible that another missing environment variable is causing this issue. You need to find the missing variable and add it manually to the registry.

3. Install Visual C++ Redistributables

Many applications require Visual C++ Redistributable in order to run properly, and if this component is missing you might encounter The system could not find the environment option that was entered message.

Users reported that this error usually occurs when trying to start a specific game, and if that’s the case, you can find the necessary files in the _CommonRedistvcredist directory.

This directory is located in the game’s installation folder, and you just have to run the setup files from vcredist folder to fix the issue.

Expert Tip: Some PC issues are hard to tackle, especially when it comes to corrupted repositories or missing Windows files. If you are having troubles fixing an error, your system may be partially broken. We recommend installing Restoro, a tool that will scan your machine and identify what the fault is.

In case you’re trying to start an application, you might have to download the Visual C++ Redistributables manually. All necessary files are available from Microsoft’s website and you can download them for free.

Keep in mind that there are many versions of Visual C++ Redistributables available, so you might have to download some older versions as well, depending on the application you’re trying to run.

These components come in both 32-bit and 64-bit versions, and if you’re using a 64-bit system you’ll need to install both versions. After installing the necessary redistributables, the problem should be completely resolved.

4. Perform an SFC scan

  1. Search for cmd and click on Run as administrator to open Command Prompt from the list.
  2. Enter the sfc /scannow command and press Enter to run it.
  3. This process can take a while, so try not to interrupt it.

5. Reinstall Unifi and Java

Several users reported this problem while trying to run Unifi. According to them, they managed to fix the problem by reinstalling Java and Unifi.

After doing that, the issue was completely resolved and they were to access Unifi again without problems.

If you’re having this issue with any other application, we suggest you reinstall it and check if that solves the problem.

6. Modify your registry

  1. Start Registry Editor (check solution number 2 for instructions).
  2. Navigate to the following path: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesLanmanServerParameters
  3. In the right pane, right-click the empty space and choose New and select DWORD (32-bit) Value.
  4. Enter IRPStackSize as the name of the new DWORD and double click it to open its properties.
  5. In the Data Value field enter the value that is appropriate for your network and click OK (the supported values are from 11 to 50).

Note: Modifying the registry can lead to system instability, therefore we strongly advise you to create a backup in case anything goes wrong.

Keep in mind that these issues occur while working on C# projects meaning that this solution won’t work for most standard users.

7. Copy msvcr71.dll to the Tomcat installation directory

This solution applies to developers that use Java and Tomcat. If you’re not a developer and you’re not using Tomcat, you can skip this solution.

Several developers reported this issue with Tomcat, but you can fix it by copying msvcr71.dll from the Javabin to Tomcatbin directory on your PC. After doing that, you should be able to use Tomcat without any issues.

If this problem doesn’t appear in Safe Mode, it’s likely that your user profile is corrupted, but you can fix the problem by creating a new profile.

  2. Go to Accounts section, then to Family & other users, and click on Add someone else to this PC.
  3. Click on I don’t have this person’s sign-in information.

  5. Enter the user name for the new user and click on Next.

Note: After creating a new user account, check if the problem appears again. If not, you’ll have to move your personal files to the new account and use it as your main account.

If the problem is still there, you might have to reset Windows 10. Read on to learn how you can do that.
