--- Comment #29 from Michael Stefaniuc mstefani@redhat.com 2013-01-30 16:44:37 CST --- Ok, "Janosch Vorschule 4 Englisch" is affected by a different bug. I tried to run it with 5e37c1a2b77cc40a1b7f896da65b57b4baa13390^ aka right before the regression commit and I still get this: err:msi:ITERATE_Actions Execution halted, action L"GetSetInstallMode" returned 1603 but now followed by tons of stuff similar to this: err:msi:ACTION_RemoveFiles removing installed file L"C:\windows\system32\asycfilt.dll" optgraph.dll is still the only file installed but I'm left with some more directories now.
Anyway, it is up for the OP aka MisterE to confirm if this bug is fixed for him. I'll open a separate one for my program.
