PSIcapture Uninstallation Error: Called RunScript when not marked in Progress during Uninstall

Problem:

In a Windows 8 environment, when attempting to uninstall PSIcapture, the installer may error and fail with the following two errors: 

"Called RunScript when not marked in Progress" followed by "Called InstallFinalize when no install in progress"

Solution:

In order to uninstall a program with this issue, you need to identify the .msi file that it uses.

1. Press the Windows key + R to bring up the Run dialog.
2. Type in C:\Windows\Installer and press Enter.
3. Right click in a blank space and click View - Details.
4. In the Details view, there are columns. Right click anywhere on the column bar and click More…
5. In the list, find Subject. Check it and click OK
6. Click the Subject column to sort the program names in alphabetical order. You should be able to identify which file is the the PSIcapture MSI file.
7. Open a Command Prompt as administrator.
8. Type in C:\Windows\Installer\ followed by the file name of the program you want to uninstall and “.msi”.
9. In our example, the file is 54c55 so we would type in: C:\Windows\Installer\54c55.msi
10. The uninstaller will now run and should complete successfully. You can close the Command Prompt when you are done.
