Hi Guys, I'm having this issue on our build server while using msbuild to build a VS2012 solution. The solution builds fine in the VS2012 IDE and via msbuild on my PC (Win 7), and builds only in VS2012 on the Build machine (Win 2008 R2). It fails with "Failed to load ISWIBuild" error when using msbuild on the build machine. The command line I'm using is: msbuild /m SolutionName.sln /p:DeployOnBuild=Yes;PublishProfile=FileSystemDeploy;Configuration=Release;Platform="Any CPU";MvcBuildViews=False The error is (path and solution names truncated for easy reading: C:\...\SomeInstaller.isproj" (default target) (26) -> C:\Program Files (x86)\MSBuild\InstallShield\2012SpringLimited\InstallShield.targets(96,3): error : Failed to load ISWIBuild: -2147221164 C:\Program Files (x86)\MSBuild\InstallShield\2012SpringLimited\InstallShield.targets(96,3): error : Exception Caught I've checked the InstallShield.targets file and it has all the correct paths as far as I can see. ISWIBuild.dll exists in "C:\Program Files (x86)\InstallShield\2012SpringLE\System\". Everything is running as Administrator (UAC Turned off). I've spent the last two days trying to figure this one out. Any help is appreciated before I lose all my hair!
