Description:

When installing CA ERwin DM I get, “Error 1500: Another installation is in progress. You must complete that installation before continuing this one.”

Error Message:  Error 1500: Another installation is in progress. You must complete that installation before continuing this one. 

Solution:

This is caused due to incomplete installation of previous application on Windows machine. This is a general MSI (Microsoft Installer) error and not actually due to ERwin.

To fix this reboot the machine and try to install ERwin and if the error still occurs follow below steps to fix this:

Note: You should have admin privileges on the system to perform below steps.

Step 1: Open Windows Registry Editor by typing regedit.exe in Start>Run.

Step 2: Go to the location: HKEY_Local_Machine\Software\Microsoft\Windows\Installer\InProgress

Step 3: You'll find that the value (Default) is filled with some data. Double click to open it. Empty the contents for that value.

Step 4: Open Windows Services by typing services.msc in Start>Run

Step 5: Find out the service named Windows Installer from the list of available services. The service would be started and Startup Type will be Manual. Right-click the service, select properties and change Startup Type to Disabled. Click Apply and then OK.

Step 6: Restart computer, after closing all the open windows.

Step 7: Once the system is up after restart, open Services, and change the Windows Installer Startup Type to Manual (You Disabled it in Step 5). Click Apply and then OK.
