After a change in the configuration we keep getting CryptoAPI cryptographic service provider (CSP) errors. I have seen a lot of references and aswers on the aspose forums, but since our configuration is different those answers are not enough.
We are using Aspose.Excel version 2.8.01. from a website running on a Windows 2003 server. The website uses a dedicated application pool.
When the identity of the application pool is set to the 'predefined network account' the answers on the forum are sufficient to solve these errors. The problem is, the identity of the application pool must run under a custom (network) account. When i login interactively on the webserver using the custom acocunt the website can create excelfiles, but as soon as i log off the CPS errors occur again.
