You have been reporting this since (at least) April and if it has not gotten any traction since then (IMHO) it probably will not.

Hello,

I want to report an issue which I think is a Windows bug introduced by one of the Windows updates (unfortunately I wasn't able to find out which one of them).

First of all this issue was already posted in the following forums sections:

http://answers.microsoft.com/en-us/windows/forum/windows_8-windows_update/every-patch-installation-fails-after-installing/e5371497-702b-455f-b31a-b2eca047763d?tm=1428478516479

https://social.msdn.microsoft.com/Forums/en-US/dc4b6e86-ec01-4a51-a6ef-d13a57818cb6/every-patch-installation-fails-after-installing-windows-updates?forum=vssetup

Please do not redirect me again to another useless Microsoft forum.

Once again, here is the test case:

1. install a fresh copy of Windows (7, 8 or 8.1 x64) on a test machine
2. install all available (important and optional) Windows Updates (so the system is up to date)
3. create a sample MSI installer which only installs some dummy files (let's say ProductVersion 1.0.0) and host it on a web server

4. install the MSI from the online location using a command line like this:

msiexec /i http://server/share/package.msi

5. create a .MSP patch (e.g. ProductVersion 1.0.1) which only adds a new file to v1.0.0
6. install the v1.0.1 patch

RESULT: the patch installation fails with the following error message: "The filename , directory name , or volume label syntax is incorrect"

NOTES:
1. the issue was replicated on Windows 7, 8 and 8.1 machines UP TO DATE (all possible updates installed)
2. the issue is not replicated on a fresh installation of Windows without Updates applied

If it needed I can send you a test MSI and MSP package which you can use in your tests.

NOTE: the issue is ALWAYS replicated by iterating the test case I posted.

Regards,
Daniel

create a sample MSI installer which only installs some dummy files...the patch installation fails with the following error message: "The filename , directory name , or volume label syntax is incorrect"

If Microsoft-created .MSI packages successfully install, perhaps something's amiss with the sample MSI packages you've created?

Hi Daniel,

Just as Robear clarified, have you tried to test this issue with the msi package downloaded from Microsoft  instead of the package you have developed?

If you suspect this issue is caused by specific update, we could perform a system restore then install the update one by one to have a troubleshoot.
