Running ILMerge on new PC. Worked fine on other PC, but now it exits with error -2146232576. Why?
-2146232576 decimal is 80131700 hex.
Error 0x80131700 is "improper installation of .NET framework"
Turns out that ILMerge needs .NET 3.5, which I didn't have installed.
Once I installed the 3.5 framework the error cleared and ILMerge ran successfully.
