To configure IIS to run 32-bit applications you must follow these steps   Open IIS Go to current server       Application Pools Select the application pool your 32-bit application will run under Click Advanced setting or Application Pool Default Set Enable 32-bit Applications to True  This solution worked for me  thanks

If you don t see log4net dll in  systemdrive  windows assembly  on the machine you are attempting to deploy it on  it is likely you haven t successfully installed the redistributable for Crystal Reports for  Net Framework 4 0  Install  or reinstall  the latest service pack from http   scn sap com docs DOC-7824  SAP Crystal Reports  developer version for Microsoft Visual Studio Updates  amp  Runtime Downloads   That runtime distribution should add log4net to the GAC along with a bunch of CrystalDecisions dll s

For this specific error  I installed version 20 of Crystal Report and it solved my problem  https   www tektutorialshub com crystal-reports crystal-reports-download-for-visual-studio  Service-Pack-16  You can also download the file alone using the following link https   www nuget org api v2 package log4net 1 2 10 rename the file to  zip and extract it

So in general dll has to be placed in two places    GAC   can have 32 and 64 versions of dll s   your project bin     folder   Thus  you just need add reference to log4net dll    In your case 32-bit with PublicKeyToken 692fbea5521e1304   You can achive that by   downloading log4net dll separately and add reference to it dowloading SAP crystal report SDK  32 bit  https   wiki scn sap com wiki display BOBJ Crystal Reports 2C Developer for Visual Studio Downloads
