Need Help Getting Old Software Program Running After Data Restore - BDE Error

I have a client who has an old software program that was on a computer that crashed.  They had a data restoration company restore certain pieces of data they could not easily replace.  One of them was the directory that houses an old software program by the name of "ProLinx."  I cannot find much on the web about this program at all.  Regardless, they need to get it running again.  Whenever you try to run the executable you get the following error:

"Exception EDatabaseError in module PROLINX.EXE at 0017:11EB.  An error occured while attempting to initialize the Borland Database Engine (error $2108)."

I have tried installing various versions of BDE from different sources online and I've done what I believe is neccesary to verify BDE is running (check the registry for the Borland entry, registered the dll I found in online write-ups, etc) and I can't seem to make any progress with this error.  Can anyone provide any input at all?

Thanks in advance!

It might be the 16-bit version of the BDE which you need.  This uses a directory called C:\IDAPI.  The configure progran is called BDECONFIG.

Have you tried this version?

I believe I have tried the 16 bit version because I have a directory called C:\IDAPI and I do have a bdecfg.exe file in that directory, however when I run it from a command line it launches a new window and I get a "System Configuration Not Found" error message.  

As for your second comment, do you happen to have a download link?

It appears to be the same as what I had in the Adapi folder.  This installer actually hangs on "writting iadpi.pak" everytime, I assume that may be an incompatibility with Windows Vista.  Either way, it still writes the Idapi directory just fine but I still get the same error when running it.

Is there anyway to tell from the raw files in the directory if this program wants BDE 16 bit or 32 bit, or something additional all together?  I tried googling the error message I get when running the .exe and it seems to have a lot of responses that I have already tried.

Thanks in advance!

Vista?  That's probably the reason.  Ye 16-bit BDE nearly got a mention in the Domesday Book (it was designed with Windows 3.1 in mind).  I reckon if you try Windows XP you will not have this problem.  I'm supporting 16-bit apps and they work fine with XP.

Sorry to say, I couldn't get it to work on XP either.  :(

Is there anyway to verify what version of Borland this program needs by the error message?

Do the database files have DB or DBF extensions?  You can view these using Database Desktop (DBD or DBD32), unless the files are Paradox (DB) and have been password protected.

The client seems to think the software is 5-7 years old.  Which means it could be from the Windows 2000-Windows XP era unless they bought it and it was already old software.

2108 is a common error.  Are you running a firewall type program on your pc which might be interfering?

Nope, I've tried it on multiple machines with and without a firewall.  I did some digging and I found something interesting.  I found there is an IDAPI folder within the program root folder that was salvaged by the data recovery company.  It looks to be a 32 bit version of Idapi.  I'm going to try to copy and paste that idapi.cfg file from that directory to my IDAPI directory and see what it shows in bdecfg.  It at least seems to point towards it being a 16 bit app.

Can't you go back to the data restoration company and ask them for directory listings for certain directories?  Not for them to undertake further recovery, but to determine whether this is a 16-bit or a 32-bit app.

Well I got the program to launch now.  What I did was copy the idapi.cfg file from the IDAPI subfolder in the program app to my c:\idapi folder.  When I do that, I then see a alias for the program name in bdecfg and I am able to launch the program.  The problem is, I get errors in just about every feature of the program that reads "cannot load driver" and then "cannot load idapi service library"

Any help?  Thanks for sticking with me thus far.

You could try reinstalling the BDE program again.  What you may have is a more modern DLL or something which is not being overwritten by an older version which is more compatible with the program than the newer version.

Go into the sysinternals.com website and download - I think it's - process monitor.  This tells you when a DLL is being called what it's looking for inside the DLL and whether it successfully finds it.

Is the IDAPI Service Library it's speaking of part of the 16 bit installer you sent me?

procmon.exe is what you want.  Start by stopping the capture of events, clear the display, prepare to run Prolinx, then start capture, then crash the program, stop the capture.  Go to the bottom of the captured data and work your way up to where the error occurred.

It's an all-or-nothing type thing - install the whole thing.  This is the entitre "database engine".

Okay, I am very close!  I started from scratch on a Windows XP machine and installed the 16 bit BDE you supplied and then dumped my clients program into c:\prolinxg and ran the executable.  It launched the application without the IDAPI service library error, but now I get the "Unknown Database. Alias: Prolinx Data."  and I also get a seperate error message window at the same time that says "Directory is busy."  

I've tried copying and pasting the idapi.cfg from the program folder (c:\prolinxg\idapi) to my system's IDAPI folder (c:\idapi) and then when I run bdecfg it shows an alias of ProlinxData pointing to "C:\Prolinxg\PSsource" as the path which seems to be where the data is.  

Can anyone shed any light on this?  Is there somethign else I need to be doing to register the alias with the BDE?  It shows up as an alias under bdecfg but I guess that's not enough.

Thanks!  I am much closer!

Nevermind, it works!  I'm going to give the full points to you obviously!  I had it right with the alias, the only problem was I did not restart after making the change so the BDE must not have picked up the change.  I restarted the computer which restarted the BDE and I guess upon restart it picks up changes made in bdecfg.  

It seems to run without a problem now and I can load the paradox tables!  Thanks so much, God bless!
