Q. After installation of eScan, it asks me for a reboot. After reboot,the installation continues, but it yet again asks me for a reboot!!!How should I get over this problem?
A. This happens because of incomplete eScan installation or improper uninstallation of an earlier version of eScan.
To overcome this problem, do the following:
- When eScan asks for reboot, *do not* click on Yes or No.
- Come to the MSDOS prompt, change directory to the eScan\TEMP folder and
- run the command "AVKWCTL /unregserver". Exit out of command prompt & then click on Yes (for the question "reboot to continue installation?").
