BTW there will be yet another avast program update tonight so you may actually hold fire till tomorrow.
Ok, so now that version 4.8.1296 is uploaded, I tried a complete reinstall. First I ran the uninstall program (aswclear.exe) from Safe Mode, rebooted, and then ran the install program, only to receive an installation error. The log reports (among other things):
30.11.2008 03:21:12 file: Extract: tried to extract 'LangMai.dll' from pkg 'av_pro_dll409' but failed miserably. Error code 0x00000057
I also got numerous lines such as:
30.11.2008 03:20:57 package: IsFullOkay: vpsm-8112700.vpu - not okay (doesn't exist)
Several days before I tried to reinstall an earlier version (avast4.8.1229.80923) which I was able to install before, and got the following errors:
26.11.2008 10:30:15 file: Extract: tried to extract 'aswRdr.sys' from pkg 'av_pro_core' but failed miserably. Error code 0x00000057
26.11.2008 10:30:16 system: Error copying driver file E:\WINDOWS\system32\drivers\aswSP.sys (0x00000002)
I tried to install again and got yet another error:
26.11.2008 12:09:10 file: Extract: tried to extract 'aswCmnOS.dll' from pkg 'avscan' but failed miserably. Error code 0x00000057
Ok, so it appears that due to randomly varying errors, I can no longer install Avast at all... anyone got any ideas what is going on here?
