You could use portable version as a test, but after you found out the problem in your system I advise the installer.
Officially Electrum should work fine on Windows 7+, if you have all the updates made, but I didn't use Electrum with older OS so I can't tell.
However, you asked about previous versions. On the download page there's a link to previous releases: https://download.electrum.org/
Just make sure you don't go back to anything before 3.3.4
