Assembly Resolve Anomaly-Please Help

Hi,

We've run into a problem that have stumped us, and was wondering if anyone
else has encountered this.

We have a product (Windows Service) that supports a plugin architecture.
Assemblies are loaded from disk at startup. This works fine normally, but for
one of the plugins on a few machines it's assembly cannot be found.

We get the the text below from the fusion log. It seems that for this
specific assembly it only searches in system32 and not in the private
assembly path.

As said - this is only one out of many plugins, and all the others work -
also it only occurs on a few machines - no noticable configuration
similarities on the ones it fails on. If I place the DLL in system32 it works.

Any help appreciated.

Hi ResultmakerMSDN,
Thanks for your waiting.

I haven't met such issue so far. In general, I'd like to suggest you add
your DLL into GAC. This will be a good solution. According to your
description and fusion log, .net framework runtime searched in system32
folder and fail to load Assembly.

It could also be a problem with your account privilege. What is the account
your windows service runs on? If this account hasn't enough privilege to
load your assemble, for windows service application, .net runtime will look
into system32 folder. Additionally, I suggest you may use FILEMON for such
File Access Privilege Issue. FileMon will log which folder does application
access and whether there is a privilege issue.

Hope this helps.
