>Basically, your screwed.
Technically, it looks like your evaluation is accurate. I was going to try InstallShield Limited, but when it started the 60MB down I cancelled it. I'm sick of their quirky proprietary stuff anyway. Do they still have their own weird scripting language? I tried using VS2012 devenv.exe to build the vdproj file from the command line, but it can't be tricked. I spent 20 minutes reading the WiX documentation and it looks like that's the way out of this dead-end. I will have to convert the vdproj files to WiX XML and replace my Custom Action code with theirs (luckily a lot of it looks like standard extensions to WiX). Sadly I know it will take dozens of man-hours of spare time to get fluent in WiX. Downloading now... The lack of vdproj support really took me by surprise. I just never saw anyone mention this matter anywhere (not that I was looking). I'd be angry about this normally, but I think I'm becoming desensitised, it's hard to not be disappointed these days Greg
