Error code 0xc0070643

Hi Lisa, I have had a similar experience with the AVG Free version suddenly refusing to update the definitions beginning on May 2nd. The repair-install did nothing to fix the problem. I un-installed AVG, ran the cleaner, restarted, deleted the remover, re-installed 5 times over the last two days and still the same 0xc0070643 error code. – Michael

Have you installed any other third party antivirus program on your PC?

Keep getting error code 0xc0070643 event exec finished. when installing AVG ulitmate Zen.  I uninstalled AVG, ran a malaware program. Tried installing different AVG downloads (free, internet secuirty etc) all get the same response. I have wasted too much time and no help over the phone, AVG just want money to fix my computer. The AVG program was working fine last week until it stopped updating. so over AVG at the moment.

This took some time to do all this and still receive the same message. No luck running remover and reinstalling ulimate. Get up to 75% and same message. Has anyone actually been able to load AVG after receiving the 0xc0070643 error code?
