Failed to connect to database: Cannot load dll

[BoyuanLu]

Hi,

I have encountered with errors when I want to import the Personal geodatabase. I didn't have such errors before, and it just pops up after the weekend. Does anyone know how to deal with this?

Hi @BoyuanLu, it looks like you posted this to ArcGIS Online section. You might have better luck posting on ArcMap.

Some troubleshooting questions:

• Have you tried the steps in this article: https://support.esri.com/en/technical-article/000013670 and on this documentation page: https://desktop.arcgis.com/en/arcmap/10.3/manage-data/databases/troubleshoot-connections.htm
• Can you open/connect to the database outside of ArcMap? 
• Have you updated your OS recently?
• Is the database a replica?
• If you revert to a previous version of the DB does it open?
• Is MSJet the latest version? If not, can you upgrade it?
