On all of our 64-bit machines, only the 64-bit software is listed on the Software tab. There is no 32-bit software listed at all, which also means these machines get flagged in the "Workstation: All workstations without Anti-virus software" report.
The thread at http://www.lansweeper.com/forum/yaf_postst763p2_Software-scanning-on-64-bits-systems.aspx claims that Version 3.5 fixes this, but we are running 4.2.0.60 and it still doesn't work.
See screenshots below for example...
Office, Java, Sophos, and Infor Worktop are all 32-bit, but do not show up in LanSweeper for this 64-bit machine.
