just sick of problems with fsx and 737 ngx now.

 

its not letting me install the spc1 600 700 getting a message saying...

 

the setup has detected that no version of the PMDG 737 6700 NGX RTM is installed.

 

this update requires that a previous version of the application be installed

Are you running Windows or a Mac?

 

If Windows, since you're early in the install stages, make sure you install FSX into its own folder such as C:\FSX and not in the normal C:\Programs (x64) or C:\Programs folder. There will be data file write problems. I didn't know this when I first installed FSX onto my Win7 gaming machine and then I did an uninstall and re-installed into C:\FSX.

 

I too had some issues with installing the service pack(s)...one of them said it was already installed (not the spc 1 one) but I had actually not done that yet so I skipped it (no choice) and moved on to installed spc 1.

Make sure your base package is fully updated and both products have been activated.

Looks like you only have downloaded the service pack itself. You will need to install the 6/700 files first. ie. download the complete installer, not just the incremental update.
