Environment variable should probably be partially removed
The indicated environment variable is typically used as a list of folder paths, in which additional paths are added at the end, and only the additional portion is removed during uninstallation. However, you specified that the variable's existing value (if any) should be removed in its entirety, which may cause problems on the target system.
This message is generated for environment variables with the following names (case-insensitive):
INCLUDE, LIB, Os2LibPath, PATH, PATHEXT, _NT_SYMBOL_PATH
You should review the situation and either change the Install action or Remove action to Remove partial value, or convince yourself that the environment variable in question can be safely removed in its entirety.
