CCS/CCSTUDIO: CoCreateInstance falied Error

Sorry, the Code composer studio version I'm using is CCS 5.2.0

Hi Charles,

What setting accidentally changed? A CCS setting, a Windows setting? etc?

Todd

Hi Todd,
I was working on the project properties on CCS, but I could not understand when the error started to occur. I was hoping that from the error message I showed someone could suggest where to act into the CCS settings.
As long as I was working on my project, If I try to import any other project with a .tcf file I get the error (even the examples code one provided with ccs).
I didn't change directories or modified file on windows.

Let me know if there is something else I can do to help explaining my issue.

Thank you
Regards

Hi Karles,

The person that knows this area the best is out the rest of the week. He'll get back to you early next week, but it might be best if you post a reminder on Tues if you have not heard back from us.

Todd

Ok Todd,
I'll be back on this post if I don't get back from you by Tues.

Thank you

Hi Karles,

It looks like something got corrupted in your Windows registry that has to do with the DPS/Bios Configuration Tool. That's why you are able to open file successfully on a different computer.

Can you uninstall and then reinstall CCS 5.2.0 and try again to open the .tcf file?

If that doesn't work we can dig into your registry and try to figure out what's wrong.

Joseph

Hi Joseph,
yes I can do that and I will let you know.

Thank you

Hi Joseph,

I did unistall and then install back CCS 5.2.0 but the same error apper.

Still, if I import the same project on a different computer everthing works.

Compilation still ends up successfully, the problem is just on the tcf editor tool.

I have multiple CCS versions installed on my  desktop (CCS 5.2.0, CCS5.5.0 and CCS7), organized as follow:

I have the same error if I open the procject with a different CCS version installed on my computer.

The error started to show up when the other CCS installation where already installed and I didn't install new plugins or software.

Here the Tconf settings I'm using:

I checked and hiervw.dll is  at the directory linked by the "import path" showed into the Tconf setting.

I'm running into a Windows10, 64bit, but I was able to correctly work on my projects from the beginning of the installation, till the error started to show up.

Is there something else I can do to?

Thank you

Hi Karles,

Can you run regedit, and select the top "Computer" item and the select the "Edit->Find" menu item, check the "Data" checkbox and search for "hiervw"?

If it is registered properly,  it should eventually find a numeric key {71D775785-71E....

If you expand the key, there will be an InProcServer32 key, that will show the location of hiervw.dll on the right hand side.

Please let me know what if/what you find.

Regards,

Joseph

Hi Joseph,
I'm sorry but I don't understand how I am supposed to find the numeric key you described.
I can tell that form my computer directory I can find the hiervw.dll file at each installed bios version folder:

C:\ti\bios_5_42_01_09\packages\ti\bios\config\gconf\bin
C:\ti\bios_5_42_02_10\packages\ti\bios\config\gconf\bin
C:\ti\bios_5_41_13_42\packages\ti\bios\config\gconf\bin

How do I find the key related to the hiervw.dll? Does the steps you described have to be followed from Code Composer Studio or straight from Windows?

Sorry, but I really wasn't able to realize how to see that key.

Thank you
Regards

Hi Karles,

Run "regedit" from a Windows command prompt. Then select "Computer" item and the select the "Edit->Find" menu item, check the "Data" checkbox and search for "hiervw":

Keep searching and look for a value like this:

If it is found, let me know the location found for hiervw.dll.

Also, did this problem start to happen after you installed a specific version of Code Composer Studio?

Regards,

Joseph

Karles,

My screen shots  didn't get posted. Here they are:

Hi Joseph,
sure!, sorry I didn't get you were referring to "regedit"! I follow your steps as soon as I will get back to my office.
Thank you

Regards

Hi Joseph,

I was finally able to follow your steps.

Here is the result of my search, icluding the location of hiervw.dll

The problem didn't show up after a new CCS installation, but I do have multiple installed CCS versions: CCS 5.2, CCS5.5 and CCS7.4

Let me know if there is something else I can do to help solving this issue and thank you again for your support!

Regards

Hi Karles,

If you look at the regedit location of hiervw.dll, it is under a CCS installation: C:\ti\ccs5_2\BIOS_5~1\packages\ti\bios\config\gconf\bin

This is different from the Tconf screen shot you posted. It shows: -Dconfig.importPath="C:/ti/bios_5_42_02_10/packages;"

It is also different than the locations you posted earlier:

C:\ti\bios_5_42_01_09\packages\ti\bios\config\gconf\bin
C:\ti\bios_5_42_02_10\packages\ti\bios\config\gconf\bin
C:\ti\bios_5_41_13_42\packages\ti\bios\config\gconf\bin

Can you tell me if there is a heirvw.dll in C:\ti\ccs5_2\BIOS_5~1\packages\ti\bios\config\gconf\bin?

And thank you for your patience. When this sort of registry corruption occurs, it is sometimes very difficult to resolve.

Regards,

Joseph

Hi Joseph,

and thank you again for your support! I do understand that this issue is particular, so I will follow every step you will suggest me.

The path C:\ti\ccs5_2\BIOS_5~1\packages\ti\bios\config\gconf\bin does not exist! Here is my dir situation:

Hi Karles,

Let's try registering the Configuration Tool .dll files manually in a location where they exist.

Can you open a Command Prompt and change to the directory: C:\ti\bios_5_42_02_10\packages\ti\bios\config\gconf\bin ?

Then enter these commands in the order shown:

    regsvr32 cdbconf.dll

    regsvr32 hiervw.dll

    regsvr32 objvw.dll

    regsvr32 propv.dll

    regsvr32 propv.dll

    regsvr32 uipkg.dll

If they register successfully, then start Code Composer Studio and try opening your .tcf file with the DSP/BIOS Configuration Tool from Project Explorer and let me know how it goes.

Regards,

Joseph

Hi Joseph,
unfortunately the steps you showed me didn't work.
I also tried to do it again and open a new example project (the dsp-bios example clk provided with the ccs installation) but still the same error occurs. I tried with each one of the installed ccs version ccs5.2, ccs5.5, ccs7 and the same error occurs.
If you think this could help, I can unistall all my ccs versions and install it back.

Let me know and thank you again for your support!
Regards

Thank you Joseph, I will do it and let you know.

Hi Joseph,
uninstall followed by a new install did solve my problem.
Thank you for you time, I appreciated it!

Regards

Hi Todd,
the thread is now closed, I marked it resolved since the suggestion of Joseph to re-install CCS made it work again.

Thank you
Regards
