Initially the 4.06 Assembler and 2.45 PBPW compiler has been successfully working under a WinXP Professional environment. However since past week suddenly nothing seems to work anymore. Even complete delete and reinstalltion of the whole package did not help. Any idea how to fix this ? Is this a screw up for Dos applications in the registry ?

Attached is an example error listing:
