What to do if OLM to PST Converter Can't be Installed Because .Net 4.5 is Running
“Olm to Pst Converter Pro” Windows version runs on .Net framework 3.5 version. There sometimes comes an installation problem for users who have 4.5 version of .Net framework installed.
Below follows the solution.
Windows 8 doesn't automatically have 3.5 enabled. So some of the apps that run on 3.5 allow users to install the app while also enabling 3.5 along the installation process. The app displays a message that .Net 3.5 is required and if you want to install it, check the box. It requires an internet connection.
“Olm to Pst Converter Pro” doesn't display the same message. Here's what you can do to enable .Net Framework 3.5 manually before installing the converter. This also requires an internet connection.
Go to 'Control Panel' → 'Programs and features' → “Windows Features On or Off”. There you will see a list of windows additional features. Find “Microsoft .Net 3.5” and check the box to enable it.
Restart your computer.
Now you can easily install “Olm to Pst Converter Pro” and start converting Olm files to Pst without any troubles.
