R – SharePoint Visual Studio document upload Web Test fails with Connot close stream until all bytes are written

I had this issue, none of the above worked. Couldn't even install the full version of VS2008 because Windows reckoned the install MSI was invalid.

Through judicious use of Process Monitor from SysInternals I got past the problem.

First I uninstalled anything existing on the PC to do with Visual Studio.

Then I ran the VC# Express installer with Process Monitor running. Noticed that it was using a log file in the %temp% folder called 'dd_depcheck_vcs_exp_90.txt'.

In that file, noticed the following:

[11/07/09,10:27:16] Visual Studio 2008 Service Pack 1 [11/07/09,10:27:16] This component uses the WinWFRegDW version check method. It will check for presense of Primary key AND absense of inequality of secondary key. [11/07/09,10:27:16] Primary Registry key being interrogated: HKLM,SOFTWARE\Microsoft\DevDiv\VS\Servicing\9.0; Value: SP; Version: 0.
[11/07/09,10:27:16] Secondary Registry key being interrogated: HKLM,SOFTWARE\Microsoft\DevDiv\VS\Servicing\9.0; For absense of Value: [SP] OR Version <> [1].
[11/07/09,10:27:16] Primary Version on user's machine: 0.
[11/07/09,10:27:16] Secondary Version on user's machine: 0.

Using RegEdit, I opened the key mentioned and changed the SP DWORD entry from 0 to 1. This allowed the VC# Express installer to start, it's obviously where the VC# Express install is looking for the VS2008 Service Pack level.

compare properties of working class with un recognised class. Specifically, "Build Action". It should resolve the problem.

if not let me know. :)
