when i open a program (call it "A") the windows installer window appears. it starts to install a previously installed program ( call it "B") which has been deleted about one month ago. Since B has been deleted, the error message appears- Internal Error 278 and gives the reference number/symbol. i press esc and after 2 complete repetitions, the windows installer stops and the A program works quite successfully.
i tried different solutions:
deleted program A - and re-installed it
deleted the registry names associated with the name of the program that is attempting to be installed.
deleted the config and ini files of the offending program which is the reference/symbol of the old deleted program A
did a search in windows directory for the phase/word of the reference/symbol- there was none.
any recommendations? thanks
