Windows 10 Upgrade Error: Windows Might be Installed in Unsupported Directory

When attempting to improve the present Windows 10 construct to 1809 (October 2018 Update) utilizing the ISO file, I’ve come throughout an attention-grabbing downside. At the stage of choosing system settings to be saved through the improve, the choice of maintaining private information and apps was inactive, and the wizard supplied just one improve possibility when all private person information and apps have been going to be deleted (Nothing possibility). Meanwhile the next message was displayed on the backside:

You can’t maintain Windows settings, private information, and apps as a result of your present model of Windows would possibly be put in in a unsupported listing.

windows 10 upgrade warning: You can’t keep Windows settings, personal files, and apps because your current version of Windows might be installed in a unsupported directory

At first it appeared to me that I wouldn’t be in a position to improve the Windows 10 construct from 1803 to 1809 and maintain all person information, and I must reinstall the Windows in a clear set up mode. However, the issue was solely in the truth that the improve wizard couldn’t discover default Windows 10 app folders (getting forward, I’d say that in my case they have been specified incorrectly on some motive).

You can repair the issue by modifying the registry. To do it:

  1. Run the Registry Editor – regedit.exe;
  2. Go to the registry key HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersion;
  3. Find the registry parameter named ProgramFilesDir. It should include the complete path to the listing the place the system ‘Program Files’ folder is saved. If your system is put in on drive C:, the worth of this parameter should be C:Program Files. If the system is put in on one other drive, the trail will be completely different, for instance, E:Program Files;
  4. Edit the worth of this parameter in order that it incorporates the complete path to Program Files listing in your Windows 10 set up; ProgramFilesDir path in registry
  5. In the identical manner, examine the values of the next parameters: ProgramFilesDir(x86), ProgramFilesPath and ProgramW6432Dir. If Windows 10 is put in on the C: drive, the next paths ought to be listed there:ProgramFilesDir(x86) = C:Program Files (x86)
    ProgramFilesPath = C:Program Files
    ProgramW6432Dir = C:Program Files

    Tip. Instead of paths, you should utilize Windows atmosphere variables. For instance, you should utilize %ProgramFiles(x86)% variable as the worth of ProgramFilesDir(x86) parameter, and %ProgramFiles% for the ProgramFilesPath.

  6. Close the Registry Editor, restart your pc and begin Windows 10 improve wizard once more.
The version, bitness and language of the Windows 10 picture in the ISO file should totally match the OS put in in your gadget. You can get the details about the unique system language as follows: DISM /on-line /get-intl

DISM /online /get-intl - get original system language in windows 10

In our instance, you possibly can see that the unique language of the system is French (Default system UI language: fr-FR). In some instances, in order to improve Windows 10 appropriately, you’ll want to take away all further localization packages.

Please, additionally just be sure you haven’t redirected normal Windows app folders or the person profile listing (C:Users) to a different drive utilizing symbolic hyperlinks. It can even trigger this downside.
