I could not install current version (Jchem for Excel on 64bit Excel 2010.

My system is based on 64bit Windows 7 and 64bit MS office 2010.  

Installer Information gives the message "Microsoft Excel 2003, 2007 or 2010 is required".

I would like to know when Jchem for Excel support 64bit Excel 2010.

Dear Sung Kwang,

yes, but we meant Office 2003, 2007, 2010 32 bit. Please also check this on the download side:

[Includes JChem for Excel Add-In. Requires Microsoft Excel 2003 SP3 or 2007 SP1 or 2010 32 bit and .NET Framework 3.5 SP1.]

yes, we are planning to suppport it from this year (in the second half).

If you are interested in 64 bit support of ChemAxon products the release plan was the following:

2010 sept. : 32 bit 2010 support from JChem Excel (Microsoft firstly started supporting 64 bit version of Office)
2010 nov. :  64 bit Marvin support including Marvin OLE (both java and dotnet side)
2011 sept.: 64 bit 2010 support  from JChemExcel

for the time being you can enjoy the full feature set of Office 2010 product with 32 bit (without any negative user experience or loss of functionality).

I see that there is an issue with the 64-bit version of Excel 2010.  I also experience this failure to recognise the installation.  I just acquired a new laptop running Windows 7 Home Premium 64-bit.   My problem is that I originally had JChem for excel running properly, but it started crashing.  I reinstalled both 32-bit Excel 2010 and JChem for Excel.  I am now experiencing another issue.  The plugin is disabled 'because it causes excel to function improperly'.  If i enable it, it seems seems to work, but gives a com error when I try to add a structure to the spreadsheet.  Do I need to go back to 32-bit windows, or do I have some other problem?

we do not support 64 bit Office, but 64 bit Windows with 32 bit Office yes. Could you send us exactly what Exception you get? Are other single actions working, like Convert from SMILES, or Open Structure?

Best regards,

Hi Tamas,

I appreciate the speedy response.  I think the problem is a corrupt workbook.  It had some structures from an old version of ChemOffice.  When so you think you might release the 64-bit version?

Tha nks again,

Hi Dick,

as it is described in earlier posts of the forum, probably later this year.

Best regards,
