Error Installing Backup Exec 2010 R3

Created: 02 Jan 2014 | 4 comments

I have a problem on one of the backup server. Some days ago one of our backup servers had two hard disk failures on a RAID 5 system which resulted in a boot up failure of the windows server. After several attempt I managed to recover the windows server but not the backup exec since the registry was corrupted. I tried reinstalling the backup exec but I had some error. So I decided to uninstall and reinstall the backup exec and then restore the system drive (c:) from a backup. When I am installing a clean backup exec installation, I am receiving an error and I cant find anything about it on the symantec website

 

The install failed with an Unexpected error: Class not Regstered (Exception from HResult: 0x80040154 (REGDB_E_CLASSNOTREG))

 

You help will be greatly appreciated

I would start with repairing the .NET framework:

If it keeps failing, the best option you have is to install Windows from scratch, install BE and start restoring.

If this response answers your concern, please mark it as a "solution"

...have you tried to manually delete every entry in the registry relating to Symantec Backup Exec? If not, do so and then try the reinstall again.

Thanks!

Hi all,

Thanks for your comments. 

@CraigV : Yes craig I remove every single entry from the registry but it still failed to install

 

@ZeRoCool: I tried re-installing the .Net Framework but still with error. So I took your advice and reinstalled everyrhing from scratch, and I think this was the best solution. Now I have the CAS server up and running and the backup media server up and running as well but they are clean. Now I was wondering if I do a restore or scrap the old setup and rebuild all my job with the new clean setup. What do you think?

...it depends really. If you have a small CASO environment, it might simply be better to redo the configuration from scratch.

If it is a large environment, and you have a backup of the Data/Catalogs folders, then simply restore. 

Thanks!
