JChem for excel install: functions "grey out" when

Hello,

I just installed JChem for Excel (5.3.3.165) on a machine with Windows 7 Enterprise and Office 2007. The install went smoothly. The JChem tab loads, and the Jchem for Excel splash screen pops up when I click any button. However, the buttons all grey out after I click anything, and won't come back until I've reloaded Excel. (I haven't gotten any structures into the spreadsheet yet). I've attached a picture of the screen to this post.

I've got .net 4 on the system, and have tried manipulating the Add-ons options as suggested in some other threads on this forum. I've gotten this to work on my Windows XP system at work...

Thanks; any help would be appreciated.

Dear Chris,

when the controls get into greyed out state means that "fatal" failure took place at boot up.
In many cases it means that .NET library cannot be loaded for any reason. IKVM -.NET framework incompatibility and so forth.

What you can do is to check event log in windows admin page and even better if you check the Document and Settings\Your User\Application Data\ChemAxon\JChem for Excel subfolder and look into logs

JCHEMforEXCEL_2010_07_06.jcxllog files and send us the problem listed in.

Thanks,

Viktor 

 

 

Hi Viktor,

Thanks for getting back to me so quickly. The following is the log entry that occurs when I try to click on any of the buttons on JChem for Excel. At at glance it looks like a problem with the licencse file (I've got the academic licence). Thanks!

Dear Chris,

my suspecion is that your license might be okay the problem is rather related to some structural issues with the installation. Please check what Marvin, Marvin .NET or JChem .NET API have been installed on your computer?
(It is strange that the required dll cannot be loaded from Global Assembly Cache)

I have Microsoft Excel 2007 running on Windows XP and the box turns 'grey' when I try to click on the license file or any other JChem button.

I have tried uninstalling and re-installing JChem_For_Excel_6.1.0.688 for end users.

JChem.NET API 6.1.0.180 is also present.

I have looked for the log file but I can't seem to find it.

Any help would be greatly appreciated,

Thanks

Please try to increase the verbos level to 5:

And check if the log files get created with the current date/time.

If there is no message in the log e.g.:

10:10:11 [3]INFO JCHEMforEXCEL - FIRST LOG MESSAGE FROM Jchem4XL::CConnectProxy

then it means some of our addins have been disabled. You need to re-enable them.
