Hello everybody, I have just installed FSX and then PMDG 737_8_900 on a 64 bit windows 7 based computer by following the suggestions given in Introduction document. However, no activation page show up after first run of FSX and an attempt to commence PMDG Operation Center results in an error related to (0xc000007b). Does someone know what is the problem and how to solve it? Thanks in advance. Sincerely,
