Hello.

I was able to reproduce the issue. It is caused by an undocumented behavior of a Microsoft method we are calling (ArgumentException should not be thrown by OpenExeConfiguration); but nevertheless, of course, it is still a problem.

We have a fix now. Please download/rebuild with version 5.70.1187 or later (setup program now available on our Web site, and NuGet packages on nuget.org).

This was a good catch. Thank you for reporting it.

Best regards

The issue is a big issue an it is general QuickOpc.net BUG on QuickOpc.net Version 5.70.1152. .I am sure that all the web appication that uses QuickOpc.net V 5.70.1152 face the same issue.After migrating a Asp.net application from version 5.63.246 to version 5.70.1152.1152 i have the Below error: Not that all the example Asp.net Demo application released in this version face the same issue. Note also that Instead the console application with the same library is working propertly and all the demo console ad windows applications with the same library work properly.. This issue is only on web application that use the library as is a bug of the Version. 5.70.1152.1152 Please let me know as soon as possible. This is the error that appear :"exePath must be specified when not running inside a stand alone exe" in System.Configuration.ConfigurationManager.OpenExeConfigurationImpl(ConfigurationFileMap fileMap, Boolean isMachine, ConfigurationUserLevel userLevel, String exePath, Boolean preLoad)
