You try to install Palisade software, and you get this message:
Error 1500. Another installation is in progress.
Maybe a previous installer crashed, maybe it didn't. What should you do?
First, try using Task Manager » Processes to end the msiexec.exe process, or just restart Windows. (Don't simply log off and on, but actually restart Windows.)
If that doesn't let you install, there are one or more System Registry keys telling Windows that an install is in progress. To fix this, please follow the procedure in Microsoft's Fix problems that programs cannot be installed or uninstalled.
We have also had customers tell us that they cleared the error condition as follows: run services.msc, change the Windows Installer service to Disabled, reboot, and then change Windows Installer service to Manual. (This was suggested by Another Installation Already in Progress (But it's Not). Please observe the usual caveats, as this is not a Microsoft site.)
