cant open wc3 after patchback 1.26

[F10EX]

Ive installed wc3 brand new, on a new computer, because i fucked up my old one.

It works when i play it on 1.27, then i installed replay Kit, and im familiar with it.
Ive patched back to 1.26

This error appears, ive tried every solution i can come up, c++, reinstall etc.

even If i patch back to 1.21 it works, just on 1.26a it gives this problem.

~In the eventuallity of someone having my problem.
Step 1. I installed a clean install of my game, made sure it ran on bnet using 1,27
step2. installed relplay kit
3.  opened up a replay so he automatically open and patch back.
4. got a new error, ''this application failed to start because side-by-side-configuration is incorrect''
5. typped in event in the event register and saw the detailed error.
6. To open the Registry Editor,"HKEY_LOCAL_MACHINE\COMPONENTS\Winners\x86_policy.9.0.microsoft.vc90.crt_". ( here instead of policy.9.0 I fetched the name that was in the event registrybut a different registry key)
Expand the key above.
Below that key, you should see a 9.0 key. Select the 9.0 registry key.
In the right pane, make note of the number you see in the Data column for the row where the Name is set to (Default), in case you need to revert to this number later.
Look through the list of numbers in the Name column and find the highest number.
Double-click the (Default) string value to open the Edit String dialog box.
Replace the number in the "Value data" box with the highest number you saw in step #6. Click OK.
On the File menu, click Exit to close the Registry Editor.
After completing step #8 the issue may be resolved. If you continue to see the same problem restart the computer. You may also need to follow the steps below to correct the file association error message.

Never heard of those erorrs but nice that you are able to fix it.

Which Windows do you use? might be important if someone else encounters this error.

This steps incorporate already the version, its for win7 users, if its vista, its another path to your registry key
