Error 257:5

Dear all
I had installed S7 5.4 SP1 with the other Packages like S7-F System, CFC, D7,...
Yesterday, I installed SP4 for S7. After that when I run S7, message 257:5 appears and terminate application :
" One or more objects or a type cannot be represented. Server 's7apromx.dll' for _S7A_PROJECT_CT objects could not be loaded. Make sure the required software packages are installed. "
What's the problem ?
Thanks

Hi, amfirooz,

I had this problem but could solve it!

Thisoccurredwhen I copied just S7Proj Folder from 1st computer and tried to open it on 2nd computer.

After opening I saved it on 2nd computer in S7Proj Folder. When I restarted and tried to open Simatic Manager I faced to this error!

I removed and reinstalled Simatic manager but unfortunatelythat message was there!!

SoI reinstalled windows (!) and then Simatic Manager, and when opened copied project, I didn't saved it to 2nd computer, I created new project with same Hardware Configuration and just copied BlockandSourceFolders andSymbolsto my new project.

When I restarted computer and opened Simatic manager it was working fine and no message was there!

You must usearchiveandretrieve, when you want to open a project on other computer because some files related to project is in other folders not only in S7Proj folder. when you use archive they will added to your archive.

I was trying to solve this problem 2 days full time, 4 times installing windows , 7 times installing Simatic Manager !!!!

I hope this help you.

Regards

Hello,

to be honest I never faced with this error. Just used Archieve and retrieve... Anyway, let's wait for opinion from other members. And hope you are on target. Good job!
