.NET FRAMEWORK does not install

Question

 

Hi all. Sorry for the kind of off topic thing but I need to install a software which makes me install .NET FRAMEWORK 2.0 but I just can't do that. I reinstalled windows installer 3.1, .NET FRAMEWORK 1 and 1.1 and Compact Framework 2.0 SP2 All this under Win XP SP2. In my "add remove programs" window the .NET FRAMEWORK 2.0 (2.0.50727) and a security update KB928365 are there but show no size and when I try to uninstall it I get a windows installer message stating that "This action is only valid for installed products." I tried a Microsof registry cleaner from the support website, uninstalling everything, stating fresh...the works... I never got it to install because when I do an error occurs and states "error 25015. The assembly wasn't able to install. C:\WINDOWS\microsoft.net\framework\v 2.0.50727\microsoft.build.tasks.dll due to a system error: the system could not find the destination path"

 

(these are messages in portuguese which I'm translating to english)

 

 

Can anyone help ? I'd hate to format my PC which has tons of things installed.

 

Regards,

Hi pedrocanel,

Please first try the workaround in this article: Assembly load failure installing the 2.0 Framework which described an issue similar to yours.

If this does not solve your problem, please trying the steps listed at What to do if other .NET Framework setup troubleshooting steps do not help to see if they help resolve this issue.

Hope this helps!

Thanks!

This can be an issue with the permission with the ServiceModel 3.0.0.0 registry key. Find the below link for more details
