Today I noticed that the UseNet search application from NewsHosting failed to apply the update, but fortunately I managed to find some evidence in the Windows Event Application log:
MsiInstaller,11714,None,Product: Newshosting — Error 1714. The older version of Newshosting cannot be removed. Contact your technical support group. System Error 1612.
After trying many things like: uninstalling manually the Newhosting app (which failed!), downloaded then the app from their website hoping that it’ll remove the old application and reinstall successfully, I did some research and found a workaround.
So, this worked for me (don’t forget to do a registry backup before bringing any modifications to it, if you don’t know what you’re doing contact their support first).
1. Opened “RegEdit” as Administrator.
2. Navigated to: HKEY_CLASSES_ROOT\Installer\
*** please note that 3FF79ACD9E0B37B4FAD448750FECA0
0C might be unique on each system, so basically I had to navigate through each registry key until I found the one which belonged to Newshosting.
3. Once the registry key was identified, I have altered the name of the following registry key 3FF79ACD9E0B37B4FAD448750FECA0
For example, the path to the registry key became like this:
4. After the registry key was altered, I ran again the Newhosting app, the update window popped and then the it was successful.
I have tested this only on Microsoft Windows 7 Ultimate x64 SP1.
Hope this will help someone.
UPDATE: I sent my workaround to Newshosting Support and they said thanks! Nice guys.
