New version of RAM Disk still sees the drive letter from the uninstalled old version

I have a perpetual licence of RAM Disk. I have just uninstalled the old version of RAM Disk and downloaded its latest version 26.7 to install. Unfortunately, I am getting an error message (in Spanish) saying that it cannot create the file I:\temp\is-GOOZRDAPAH.tmp because it cannot find the path:

Error

El programa de instalación no pudo crear la carpeta
"I:\temp\is-GOOZRDAPAH.tmp"
Error 3: El sistema no puede encontrar la ruta especificada.

It seems that the installer still sees the "I:" drive letter that was used in the old installation of RAM Disk.

That error isn't caused by the RAM Disk installer or your licence. Your Windows TEMP folder still points to I:\temp, which was on the RAM disk that you removed. As that drive no longer exists, the installer cannot create its temporary files there, and shows the "cannot find the path" error.

To fix it:

1. Press Win+R, type: sysdm.cpl and then press Enter.
2. Go to the Advanced tab and click Environment Variables.
3. Under User variables, set both TEMP and TMP to: %USERPROFILE%\AppData\Local\Temp
4. Under System variables, set both TEMP and TMP to: %SystemRoot%\TEMP
5. Click OK, restart the computer.
6. To verify, open a Command Prompt and type: echo %TEMP% - it must not show I:.
7. Run the new RAM Disk installer again.

Once installed, if you would like the temporary folder back on the RAM disk, use the Tools - Set temporary folder menu in RAM Disk and point it to a folder such as I:\Temp rather than the drive root.

To prevent such errors in the future, make sure that before uninstalling RAM Disk you revert all system folders, caches and temporary directories that you pointed to your RAM disk.
