Hi,I have just migrated from an XP based system to a Vista one and although the 737NG 600/700 base programme (and PMDG livery) has installed with no problems, any attempt at installing add-on liveries whether from the original CD or the PMDG website always results in an error report that the exe file has stopped working and that the relevant aircraft.cfg file could not be opened. No additional liveries will install at all.The Vista error code logged for the BMI BABY install (as an example) reports as:ProductPMDG737-600 British Midlands BMI BABY.ExeProblemStopped workingDate29/08/2008 17:17StatusReport SentProblem signatureProblem Event Name: APPCRASHApplication Name: PMDG737-600 British Midlands BMI BABY.ExeApplication Version: 0.0.0.0Application Timestamp: 3bd86c3fFault Module Name: GLC97DD.tmpFault Module Version: 0.0.0.0Fault Module Timestamp: 3d29f04dException Code: c0000005Exception Offset: 00003eabOS Version: 6.0.6001.2.1.0.256.1Locale ID: 2057Additional Information 1: 711aAdditional Information 2: f90cd731da9036c41610b3ab975a8192Additional Information 3: 093dAdditional Information 4: dc8fa42ebec3568a9e7b31f5b8bd8ee6Any ideas? I have uninstalled and re-installed the 737NG 600-700 but it makes no difference (as yet). I also have the current build of the 747 for FS9.1 installed. Anti-virus was also off and the installer "Run as Administrator". FS9.1 is not in the default location on the C drive, but in a matching location on the 'D' drive in order to avoid Vista's well documented issues with programmes accessing the default "Program Files" folder. I point the installer to the correct folder as part of the installation process.Richard

Is there really no one who has an answer to this, including from the PMDG Team?Richard
