Sources of MSP Problems


Issues Opening MSP Files

Windows Installer Isn't There

Double-clicking your MSP file prompts the message "%%os%% Can't Open MSP File". If so, it typically means that you don't have Windows Installer installed for %%os%%. Your operating system cannot associate your MSP with Windows Installer, so double-clicking the file won't work.


Tip: When another MSP application is installed, you can choose to open it by selecting "Show Apps" and using that program.


Windows Installer is Out-of-Date

In other instances, your Windows Installer Patch file version may not be supported by your version of Windows Installer. Download the latest Windows Installer version from the Microsoft Corporation website to ensure you have the correct one installed. This issue mainly occurs when your Windows Installer Patch file was created by a newer version of Windows Installer than you have on your PC.


Tip: If you right-click on your MSP file, then select "Properties" (Windows) or "Get Info" (Mac), you can obtain hints about what version you need.


Ultimately, most of the difficulties opening MSP files are due to having the wrong version of Windows Installer installed.


Other Causes of MSP File Opening Problems

Assuming you have the right Windows Installer version installed, other problems can prevent you from opening MSP files. If you are still having problems opening MSP files, there may be other issues that are preventing you from opening these files. These other problems include (listed in order from most to least common):

  • MSP file type Registry entries are wrong
  • Deletion of the MSP file description from the Registry by mistake
  • Corrupt install of Windows Installer or other MSP-related program
  • Your MSP can't be loaded properly (file corruption)
  • The MSP is infected with a virus
  • Drivers associated with MSP software need to be updated
