The bug I pointed out a couple weeks ago with the PortableGIMP wrapper (https://portableapps.com/node/1382) also exists in PortableGAIM. Basically, it breaks a PortableSuite-Style install.
Something tells me that this bug got carried over to PortableGIMP from here...
PortableGAIM.nsi; Line 153: "Apps" instead of "App"

BTW, Thanks for all your work. I've found these tools invaluable.
