Hello all,

My client's PC runs Windows 7 Ultimate with .netframework 4 client profile. I am unable to install my application developed in VS2008. I tried uninstalling .NET Framework 4 From his PC and running the Clean up tool provided by Microsoft. But still I am unable to install it successfully. It provides Error 1001.

I tried running the program as administrator. I also tried to Turn on .net 3.5 feature from add or remove program.

Thanks in advance. :)

Edit:

The error what i get is shown here.

Furthermore,

1. I have confirmed that it is a 32bit processor and i run x86 release version of setup
2. The application is developed in a Windows 7 OS with .NET Framework 3.5

3. I have installed this application in 7 PCs which have .NET 3.5 installed in them and having OS Windows XP,Vista and Windows 7; and all are working fine.

4. In clients PC, when I try to install .NET 3.5 again, the installer starts but then it disappears suddenly without doing anything

5. I have tried turning on .NET 3.5 framework feature from control panel> Program and Features.

6. I have tried running the program as Administrator
7. I have tried setting the application setup in Windows XP and Vista compatible mode.

But still the issue persists.

Thanks :)
