[Former Member]

Hi there,

I am having the above error when trying to export a report in a .Net Application on Framework 2.0.

I have found [here |https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/oss_notes/sdn_oss_boj_erq/sap(bD1lbiZjPTAwMQ==)/bc/bsp/spn/scn_bosap/notes%7B6163636573733d36393736354636443646363436353344333933393338323636393736354637333631373036453646373436353733354636453735364436323635373233443330333033303331333233303334333133383333%7D.do] an article that descripes the problem and gives as a solution to upgrade to Crystal XI release 2.

Thought, in our current application we do not use the Crystal Reports Application. We just use the embeded Crystal report utility that exist on Visual Studio.

You can found a desciption on how we deploy this [here|http://walaapoints.blogspot.com/2007/06/deploying-crystal-reports-visual-studio.html]

Is there a patch for this in order to support Framework 2.0 or we need to get the Crystal Reports Application just to enable exporting reports?

Thanks for your help.

I need a bit of a clarification. The kbase you point to regarding the error, is very specific to CR XI release 1 when it is used on framework 2.0. CR XI r1 does not support framework 1.1.

From your description, I believe you are using CR version 10.2? If that is the case, the CR assemblies you'd be using will be version 10.2.3600. Can you please check that and let me know. The error you are getting is not a known issue with CR 10.2 so we'll have to troubleshoot this a bit more. Also, from your description it appears that you are seeing the issue once you deploy the app? And the app works on your development system? Please confirm.

Dear Ludek,

Thanks a lot for your answer.

I think I didn't make this clear. We actually do not use the CR package that comes with Visual studio but a newer version of this package.

I think the Visual Studio's package install the dlls under C:\Program Files\Common Files\Business Objects\2.7.

The package we use installs the dlls under the C:\Program Files\Common Files\Business Objects\3.0\managed

The installed dlls under this directory have the version 11.0.3300.0 (This is the version that I can see when I add them as a reference in a Visual Studio project)

If i go to the directory C:\Program Files\Common Files\Business Objects\3.0\managed and click properties->version I found out the version 11.0.9500.53 for the same dll under the same directory.

Also I want to clarify again, that we actually do not have the CR Application installed. Only this kind of redistribution package that comes with Visual Studio.

Hope I make this clear.

Thanks again for your help.

As the dll's pointing that the version is 11.0.. that means Crystal reports XI R1 is in use.

would like to inform that CR XI R1 is not compatible with framework 2.0.

To make CR XI R1 compatible with framework 2.0 you need to upgrade it to CR XI R2. upgrade is free and installation file is availabe [here|http://resources.businessobjects.com/support/additional_downloads/service_packs/crystal_reports_en.asp#CRXIR2]

Click on - Service Pack 2 - Full build - ZIP - 1.03 GB - released April 2007.

Refer [thread|; for upgrading process.

hope this helps.
