"Another version of Pro Tools appears to be installed on this computer. Please use the "Add or Remove Programs" control panel to uninstall the existing version of Pro Tools and restart this computer before reinstalling Pro Tools."

The above error may be seen when you try to remove Pro Tools from a Windows system. The error usually results if Pro Tools fails to install properly.

There are 2 things you may try to resolve this:

1) Download Reg Cleaner, a free utility, that will allow you to easily remove all Digidesign items from your registry. Click here for Reg Cleaner download page (by Jouni Vuoro).

2) Try running -fix, See the instructions below:

If you cannot completely remove Pro Tools from the Windows Add/Remove Programs list, then the application has become stuck in the Windows Registry. There is a simple way to remove all Registry Keys and Drivers associated with Pro Tools:

Click “Start” choose “Run”.
  • Type in the full path to “setup.exe” on the install disc, or on the appropriate folder and hard drive if the installer was downloaded (make sure you surround the path in quotes).
  • At the end of the path, add “ -fix” (there should be a space before the –fix).
  • Click OK

It should look like this (assuming D: is the drive letter for the DVD drive):



You can also drag the setup.exe file to the Run box and it will type the path in for you. Then just add " –fix" to the end.

This will work for all Windows versions of Pro Tools 7.0 and higher: M-Powered, LE, and HD. Please note, however, that though this utility is built into the installer application, it has not been tested or qualified by Digidesign and should be used only if Add/Remove Programs does not completely uninstall Pro Tools.

Disclaimer: Please note that Digidesign does not test this fix; thus, it is not considered to be "supported". However, this fix has often been used successfully during Technical Support calls.
