* This is an older post but we ran into this issue once again.

We recently migrated a client to Kaspersky BusinessSpace Security and part of this migration was to remove Trend Micro for SMB from their Windows Small Business server.  The suite also included the messaging security agent for Exchange.  We removed the security server through Add/Remove programs and of course it seem to stall near the end and said not all components could be removed, reboot, and manually delete the program folder under C:/Program Files…After we did that we still couldn’t install Kaspersky as it said it could still see the Trend Micro installation.  After a bit of googling, we found a KB article from Trend Micro’s support database that described the process to manually remove ALL components.  After stepping through the pages of instructions we still could not install Kasperky.  Frustrated,  we decided to check Kaspersky’s forums just to see whether someone was having the same issue, and sure enough, we stumbled upon these instructions:

·         Delete this folder : C:\program Files\InstallShield Installation Information\{E0CA6191-52E8-41E0-96B2-05E A08E6869C}

·         Pay attention you should enable display of hidden files and folder to see it.

·         Then reinstall the product.
