Discovered this error on a machine today. Started when deployed a new version of a bundle on it. Then noticed it gave the same error with all the bundles on the machine.

"Unexpected error installing file. Error: Object reference not set to an instance of an object."

Zac cc didn't help. Machine running Win 7 64 bit. Zenworks version Tried removing the bundle. The bundles that remained still gave the error.

Any help would be appreciated.
