installshield - InstallShield 2011：缺少预定义变量

Question

我正在 IS 2011 中构建一个项目并收到此错误：

ISDEV : error -1024: File <ISRedistPlatformDependentFolder>\isregsvr.dll not found. Cannot stream the file into the Binary table
ISDEV : error -1024: File <ISRedistPlatformDependentFolder>\SFHelper.dll not found. Cannot stream the file into the Binary table
ISDEV : error -1024: File <ISRedistPlatformDependentFolder>\isxmlcfg.dll not found. Cannot stream the file into the Binary table
ISDEV : error -1024: File <ISRedistPlatformDependentFolder>\SetAllUsers.dll not found. Cannot stream the file into the Binary table
ISDEV : error -1024: File <ISRedistPlatformDependentFolder>\IISHelper.dll not found. Cannot stream the file into the Binary table

在“路径变量”面板中， ISRedistPlatformDependentFolder缺少该变量：

虽然它应该是这样的：（从另一台机器拍摄的图像）：

那么，如何将其恢复为预定义变量，或者如何摆脱以下错误：

ISDEV : error -1024: File <ISRedistPlatformDependentFolder>\isregsvr.dll not found. Cannot stream the file into the Binary table

谢谢
