Windows 10: windows 10 version 1903 .net framework issue

Right after having installed 1903, when starting to index with Lookeen a parser error window appears every few seconds requiring .net Framework v4.0 to be installed. The very same error appears also when trying to start up the Copernic index service.

Trying to install the .net Framework version 4 stalls ends with a message that 1903 has .net Framework embedded already and as a newer version, so the older didn't get installed.

How to solve this deadlock, which to me would seem a Windows-10-1903 bug, not something specific for the index servicing Lookeen or Copernic apps.

Microsoft .NET Framework, Unhandled exception

Hi,

Welcome to Microsoft Community.

I suggest you to un-check and recheck .Net framework 3.5 and .Net framework 4.6 advance series from Windows features.

Try the following steps:

• Press Windows + R keys to open Run command.
• Type Appwiz.cpl and select "turn Windows feature on or off" from the left
• Uncheck .Net framework 3.5 and .Net framework 4.6 advance series.
• Restart the computer
• Repeat step 1 and 2 and check .Net framework 3.5 and .Net framework 4.6 advance series.
• Restart the computer.

Regards,

 

.net FRAMEWORK version 2.0

No it didn't help. When I opened the dialog box that you are referring to, the "(NET Framework 3.5(includes .NET 2.0 and 3.0)" box was already ticked/darkened. I went ahead and restarted my computer again just in case. When my computer restarted, I got
the small pop up box that said that the "net Framework version 2.0" had not been installed. Any other ideas?
