Firewall

A personal firewall running on the same computer as AppScan can block communication and result in inaccurate findings and reduced performance. For best results do not run a personal firewall on the computer that runs AppScan.

Antivirus

An antivirus program running on the same computer as AppScan can impede scanning. For best results do not run an antivirus program on the computer that runs AppScan, or at least make sure that AppScan is added in its list of approved programs.

Multiple instances of AppScan

You can have more than one instance of AppScan open on the same machine, for example to compare scan configurations or results, but only one scan should be run at a time.
