Question

When ever I am trying to install .Net framework on my machine (Vista 32 bit machine) it gives above error.

Even after «Turning on or off windows features» through control panel, it continue giving the same error.

Has anybody faced this issue befor?

Answers

What .NET Framework version are you trying to install on your machine? Vista already has .NET Framework 3.0 as an OS component in it. So if you are trying to install a version lower than .NET Framework 3.5, you will see this message. All you would need to do in this case would be to goto Control Panel -> Programs and Features -> Turn Windows features on or off -> Check the box next to Microsoft .NET Framework 3.0.

Solidsnake 89. here ya go . Had the same exact problem. DROVE ME NUTS FOR DAYS. after much searching got clue from another.

Find a computer (my laptop served me well) copied files labled framework and framework 64 (both are win 7 64 bit machines) from C:windows/Microsoft.NET folder. to thumb drive. copy and replace existing files to non working machine in same location.

I WAS THEN ABLE TO CHECK What EVER AND IT WORKS . AND turbo tax then installed also .

this way worked for me

but i download 231mb of .net framework 3.5 sp1 from microsoft web site (not 2.7bm)

hey sparks i tried to delete the frameworks for replacing them but i couldnt because an error occurs saying that

«you need permission to perform this action

You require permission from TrustedInstaller to make changes to this folder»

I will be waiting for your reply

Ah yes the dredded «TrustedInstaller». This is a generic user which is given total Administrative rights for the installation of your operating system at the time it was built by the manufacturer. I have seen this TrustedInstaller user on HP, Dell and standard Windows installs. The way to get around that is to take ownership of your hard drive and give those rights to you, using your current username. This is done by using the security tab in in My Computer. Open My Computer, «right click» on the drive «C» or whatever drive has your operating system on it. Left click properties, there will be seven (7) tabs that open up in a box. Go to the tab that has «Security» on it by left clicking it and brining it to the front, then «Advanced» near the lower right corner of this window. Click on the tab that has «Owner», click on the button that has «edit». This will open a box that should have Administrators and your username in it. Click on your username and it will be come highlighted, then make sure to click in the check box below it «Replace owner on subcontainers and objects:, then click ok. You will probably get two errors, about «pagefile.sys» and another file name of somekind. Just click ok to those and it will change ownership of the drive to your account and that should give you sufficient rights to complete the installation.

When ever I am trying to install .Net framework on my machine (Vista 32 bit machine) it gives above error.

Even after «Turning on or off windows features» through control panel, it continue giving the same error.

Solution is that : Open Control panel >>Program(Uninstall a progaram )>>then click at Turn window feature on or off>>uncheck dot net framwork 3.5.
