installation - .NET 4 fails to install because SECUREREPAIR fails to CreateContentHash of file SetupResources.dll: for computing hash Error: 997

Question

I have trouble installing any .NET Framework on my Windows 7 x64 machine, I keep getting the following logfile, what might cause this?

OS Version = 6.1.7601, Platform 2, Service Pack 1

I have pasted a LOGfile from the MSI file, can you please take a look?

The main problem seems to be the following information I found in the setup log (see line 2981 to 2999 in the log above):

MSI (s) (78!78) [16:11:30:749]: SECUREREPAIR: Failed to CreateContentHash of the file: 1033SetupResources.dll: for computing its hash. Error: 997

The only information I found concerning problems with Secrepair is KB2918614, which I completely uninstalled, rebooted, but the problem persists. Furthermore, I have reinstalled KB2918614, applied its Hotfix (KB3000988), and the problem still persits.

It happens with .NET Framework 4.0 and 4.5, no matter which of these I try to install.

I first noticed this problem when trying to apply the update for .NET 4.5.2, which failed, so I uninstalled .NET framework 4 and 4.5 completely, and am now unable to install any of these.

Do you have any ideas what might be causing this strange behaviour?

Answer 1

The solution provided by Thaoden (uninstalling KB2918614, KB3000988 and KB3008627) didn't work for me. I got the same errors after uninstalling these updates.

What did work for me was the whitelisting workaround suggested by JohnL999 here.

So, what I had to do to make it install:

1. Create a DWORD named SecureRepairPolicy with value 2 in HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindowsInstaller

2. Create Key SecureRepairWhitelist in HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindowsInstaller

3. In SecureRepairWhitelist, create a String with the product ID you want to whitelist as name. In my case this was {3911CF56-9EF2-39BA-846A-C27BD3CD0685}. You can find out the product ID in the msi log file, some lines before the error

   SECUREREPAIR: Failed to CreateContentHash of the file: 1030SetupResources.dll: for computing its hash. Error: 997.
   

   It looks like this:

   SECREPAIR: Hash Database: C:windowsInstallerSourceHash{3911CF56-9EF2-39BA-846A-C27BD3CD0685}
   

   or this:

   SOURCEDIR product ==> {3911CF56-9EF2-39BA-846A-C27BD3CD0685}
   

   Might be a different product ID depending on the MSI you want to install.
