SB v5.31.4 "The Windows Installer Service Could Not Be Accessed" when trying to install programs.

So I installed v5.31.4 the other day and everything seemed fine, but now though, I'm trying to install Mumble 1.3.0 and I'm getting this "The Windows Installer Service Could Not Be Accessed" error message.

Can anyone else confirm? I don't know if it was from going Beta 5.31.2 to 5.31.4 change that is now showing me this error or if it's a Windows 10 issue... I'm on the latest W10 1903 build also 18362.356.

Here's the download links for Mumble for you guys to try, let me know if you can get the msi installer to work... let me know your OS build version and SB version too would be helpful.

I'd like to know if this works for 5.31.2 but not 5.31.4, or does it not work for both?

Also anyone know where I can download the beta version of SB 5.31.2 in case I need to downgrade to fix this regression?

  • Hello,

    Same situation, it seems that the latest windows 1903 updates changed something and sanboxie lost the ability to install software. Any software already installed in a sandbox works fine. Tried some online suggestions to try to fix windows installer service in sandbox but none of the worked. Let's hope that someone finds a workaround or maybe a fixed version from sophos because at the moment sandboxie is badly crippled.

    Um, I can install for example "CCleaner" executable installer sandbox'd.   I cannot install ... msi installer....sandbox'd....same as opening poster.
