Failed to load tcom

Failed to load tcom

Failed to load tcom

I am trying to use tcom to run an Excel macro from tcl.
There are several posts on the forum in various states regarding this.
I have downloaded version 3.9 tcom from:
And put the files where indicated. However the next step:
package require tcom
Does not work. I get the following error message:
couldn't load library "C:/Tcl/lib/tcom/tcom.dll": invalid argument

I can go to the directory and see the tcom.dll file, it is there are is readable.
I have also tried a suggestion to use:
teacup install tcom
I get this long error:
Resolving tcom ... Not found in the archives.

While a more fuzzy search disregarding letter case and accepting
substrings was done, we are sorry to say that it yielded no possible
candidates for installation either.

Questions to consider:
Have you spelled the name correctly ?
Including the proper case of characters ?

Note that teacup's 'search' command allows you to locate packages by
subject, categories, and the like.

Aborting installation, was not able to locate the requested
I can certainly see tcom is there in the directory.

PC is running Windows 7, could that be the problem? Tcl version 8.5.12

Any help with this is appreciated.

RE: Failed to load tcom

Thanks mikrom,
I had already seen two of those links.
Are you using Windows 7?

RE: Failed to load tcom

Are you using ActiveTcl ?
I have installed tcom only on Windows XP and Windows Vista - I didn't try it on Windows 7 till now.

RE: Failed to load tcom

If you have 64-bit Windows with 64-bit Tcl installed, then maybe the answer for your problem is here:
They say, that tcom is available only for 32-bit tcl - so you should install 32-bit Tcl on your 64-bit Windows.
