PC Anywhere Install Help

Hi Everybody. I'm trying to install PC Anywhere on my iMac to connect to my work computer. My iMac is running OS X v10.5.8 and I have both Safari (4.0.4) and Firefox (3.05) installed on this machine. The work computer is running Windows XP Pro. 

 

So, my problem is that when I try to install PC Anywhere (cross platform: SetupLinuxMac.jar) both the typical and custom install options want to install ThinHost, but the total size is 0 KB. Therefore not installing ANYTHING.

 

Anybody have any suggestions? What am I missing? I do remember reading that JAVA Virtual Machine is required for this to work. Mac's have their own version of JAVA, so I don't know if this is the problem, but I have the most current version. Any help you could provide would be greatly appreciated. 

 

Thanks in advance!
