TM1 Forum

Hi,

I have installed OLAPObjects 5.0 in TM1 web and after the installation when i start access the web, i am getting error - File Not Found : TM1API.dll.

I tried registering this dll using REGSVR32. But still it throws error (please find attached screen shot).

Please help me to resolve this. Thanks in advance.

Thanks

Not all DLLs are COM libraries.

If a DLL is a COM library it will contain a function DllRegisterServer which RegSvr32 can call to make it put information about what objects it supports and how to instantiate them, along with the DLL's location, into the system registry.

Most DLLs are not like this however. They simply export a set of functions which are available to calling functions once they are loaded. The client will call LoadLibrary to load it. This takes a file name or a path name. If it is not a fully qualified path then LoadLibrary searches for it as documented here http://msdn.microsoft.com/en-us/library ... s.85).aspx.

TM1API.DLL is the second kind (which is why RegSvr32 gives you that error) but it is obviously not on the path or in the current working directory of the program that is trying to load it.

You need to find what is trying to load it and put it where that can find it. Are there specific instructions in the documentation of OLAP Objects about where it needs to be installed relative to the TM1 installation?

Yes we have to specify the path to install.

... and is the TM1API.DLL in the location that you specified? If you are using 9.5 it almost certainly won't be in the path shown in the picture.

I am using TM1 10.1.1. and the path i have chosen for TM1API is

C:\Program Files\ibm\cognos\tm1_64\bin64 as i am using a 64 bit application.

Hi:

The current version of OLAPObjects is a 32-bit application and, thus, it needs a 32-bit version of TM1 API files. The easiest way to get that is to install a 32-bit TM1 client (like Architect) and to make sure the installed BIN folder is reflected in the system PATH variable, which is what the installer is ultimately doing.

If you have any questions, please don't hesitate to let me know. I'll send you a PM as well.

thanks Mike.

I am installing as per your instruction. Keep you posted.

Thanks

Actually, I believe TM1 10 installs both 32-bit and 64-bit versions of the API (at least it did for me, with the options I selected).

There should be both a "bin64" and a "bin" folder underneath the program path.

I'm not sure how you tell OLAPObjects which one to pick, but there is likely a registry key or config file to do the job.

Thank you for all your support. I have installed and configured OLAP Objects and the system is up and running.

Thanks

Hello all,
I have and issue with a custom .Net web app I built. I'm using OLAP Objects to connect to TM1. The issue I have is that when I set the Admin Server in my TM1 DataSpace object, it doesn't find any TM1 servers. I have 2 TM1 servers up and running, but it doesn't find them. Any advice?

Hi Ben:

We'll contact you offline to assist further - it could be things like licensing, TM1 SSL settings or something similar preventing TM1 Servers from being seen via OLAPObjects and the TM1 API.
