addinSpy警告DLL路径未找到.问题与我的dll或程序集在GAC

我有一个Excel插件。它取决于我在GAC中注册的程序集。

addinSpy给出了这个警告(抱歉它不能很好地格式化)

Add-in DLL path is not found. System.BadImageFormatException: Could not load file or assembly 'file:///C:'Program Files (x86)'Poly'PolyAddins'PolyExcel'DBExcelAddin.dll' or one

我特别不明白什么"尝试下载新的URL文件:///C:/Program Files (x86)/Poly/PolyAddins/PolyExcel/DBExcelAddin.dll"失败，因为这正是它所在的位置。

所以我认为聚变是下一步尝试弄清楚发生了什么。

WRN: Partial binding information was supplied for an assembly:

WRN: A partial bind occurs when only part of the assembly display name is provided.

WRN: that consists of the simple name, version, culture, and public key token.

我肯定它在告诉我该怎么做，但我不明白，所以你能让我知道吗
