Hello. When I install pmdg 737 ngx on my fsx steam edition, I get an alert saying: fsx 10 0 6 1355 (sp1 at least required .
you have 100695 0.install fsx sp1 or later .what should I do?) if you could explain to me step by step because I'm not at all expert, even novice.

thank you all

Do you also have an older boxed version of FSX installed?  Welcome to the AVSIM forums.

not installed any old version. only one

For FSX, you need SP1 and SP2 installed - https://support.precisionmanuals.com/kb/a87/how-to-uninstall-and-reinstall-fsx.aspx

If you have the old boxed version of FSX, I would suggest buying FSX-SE which has SP1 and SP2 included. 

SP2 - https://www.microsoft.com/en-us/download/details.aspx?id=8986

I cannot find SP1.

He states that he has FSX-SE installed, so no need for the SPs.

Forgot to read the OP.  LOL. 

Alex,

Did you select FSX-SE as the install option when you first start the install?  If not, maybe the install can't find the location of your FSX-SE system.

the warning comes out immediately after loading the first window of the install shield wizard of the pmdg

I think your best possible solution is to submit a ticket with your purchase info included to the official PMDG site.

Where did you install FSX-SE?  On which drive?

Jim Driskell

c,program file, microsoft game, and inside the box fligh simulator x

 

I've read about problems installing on the C drive.  Check your permissions, and make sure you are running the installer as admin.  I had no difficulty installing 4 of the PMDG applications in my FSX-SE system but I have my system on a separate SSD D Drive.  Did you open a ticket with PMDG?  Let me know how this comes out.

I do not have the steam addition but i would hazard to guess that the PMDG installer is looking for the proper simconnect version(s).
Steam has it's own (62615) and also installs (61259 acceleration?) you can find the other 2 (RTM & Sp1) installers in following paths, or similar - run them.

C:\Program Files (x86)\Steam\SteamApps\common\FSX\SDK\Core Utilities Kit\SimConnect SDK\LegacyInterfaces\FSX-RTM
C:\Program Files (x86)\Steam\SteamApps\common\FSX\SDK\Core Utilities Kit\SimConnect SDK\LegacyInterfaces\FSX-SP1

 

You're probably right.  I do remember a message about simconnect but I didn't have any problems installing so I ignored it.  I also installed FSX-SE on a separate SSD so my experience was different than Alex.
