Allow windows installer service to start in safe mode
msiexec.exe
Sometimes it may be necessary to uninstall an application, but for one reason or another, Windows will not allow this. One approach is to try to uninstall the program in safe mode. The default safe mode does not service ”Windows Installer” turned on, which is needed to uninstall. Here is a description how to set up the system to enable starting the Windows Installer in Safe Mode. The method involves editing the registry and is more for advanced users.
- Open the Registry Editor:
- Navigate to the registry key:
[HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Minimal]- Right-click on
"Minimal"
- Choose ”New key”
- Name the key
"MSIServer".
- Change the data value
"default"to"service". The figure below shows the entry in the Registry Editor.
Start the service in safe mode will now be activated. If it is not already running, you can start the service from the command line. Open a command prompt with administrator rights and then type:sc start msiserver
If you want to be able to start this service in ”Safe mode with networking” need another registry key change. Navigate to:
[HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Network]Do the same as above. Add a new Key named "MSIServer".
