It makes the tests fail here:

err:msi:env_parse_flags Invalid flags: 00000007
err:msi:ITERATE_Actions Execution halted, action L"RemoveEnvironmentStrings" returned 1627
err:msi:env_parse_flags Invalid flags: 00000007
action.c:5899: Test failed: Expected ERROR_SUCCESS, got 1627
action.c:5905: Test failed: Expected ERROR_FILE_NOT_FOUND, got 0
action.c:5908: Test failed: Expected ERROR_FILE_NOT_FOUND, got 0
action.c:5920: Test failed: Expected ERROR_FILE_NOT_FOUND, got 0

I'd suggest to simply remove these checks.
