Hi Kel, those who are using some progies reports that they need a msdia80.dll in commonfiles\msshared\vc. Given that some Chinese programmers are not resposible enough and always releases "beta" ver, and the progie they made will automatically send feedbacks, thus in order to run these programs they need this "debug Information Accessor" dll. so can you add this in to your pack? it is in VS80sp1_KB934586_X86_ENU.exe\VS80sp1-KB934586-X86-ENU.msp\PCW_CAB_VS_10488\FL_vcredist_x86_exe_132136_____X86.3643236F_FC70_11D3_A536_0090278A1BB8\vcredis1.cab\ and original file name: FL_msdia71_dll_2_____X86.3643236F_FC70_11D3_A536_0090278A1BB8 another: a bug in your inf vcc90.copy = 16427,"Microsoft Shared","VC" should be vcc90.copy = 16427,"Microsoft Shared\VC"
