automat · September 3, 2019, 6:47pm

i have downloaded uipath studio community edition and running lots of program since last one week.

however, today when i executed the workflow, it just stops at main.xaml in a debug mode and halts the running and shows nothing.

not sure what i messed up ,but i cant run any workflow that was previously working.

see attached screenshot.dont know what is happening

Hello Sir,

Have you tried all of this?

Reopen Studio
Reboot OS
Reinstall Studio

Hope, it will help.

AndyMenon · September 4, 2019, 12:30am

Is your Main.xaml empty? What is it doing?

Did you select the option to Run File with Debug option?

automat · September 4, 2019, 12:44am

yes tried all the options ,still the same issue.

automat · September 4, 2019, 12:51am

no. just the normal option. i cannot even run a simple workflow now. i even reinstalled and checked. Still the same option. No idea whats happening.
does this error ring any bell?

AndyMenon · September 4, 2019, 2:39am

The errors show that some key elements of the installation are missing. Or some assemblies that need to already exist on your machine might be missing.

It’s not able to find Microsoft.Exchange.WebServices.Auth

You should google this assembly and see if it’s missing on your machine.
Alternately, the UiPath studio may have to be reinstalled.

Also, check if the basic packages are available in your project.

automat · September 4, 2019, 1:55pm

Thanks Andy for providing help on this. I have all these enabled. I also see one more error in log file
I uninstalled and reinstalled the UIPath. Still the same issue.

automat · September 4, 2019, 2:17pm

i am thinking i spoke too soon. i was indeed missing the Credentials.Activities. wondering how it was working earlier for the past 2 weeks.

thanks So much Andy.Really appreciate your help.

AndyMenon · September 4, 2019, 4:12pm

Awesome! Glad that it worked out.
Please mark this as Solution if it helped you so that it may be helpful to others having the same problem.

Thanks

I have a similar issue - the process actually runs ok for testing but won’t publish due to a compiler error (and the logs showed an inability to load dark theme icons).

Installing UiPath.credentials.activities has not resolved the issue. The errors in the log are:

14:35:29.0535 => [ERROR] [UiPath.Studio.Project] [6] Failed to resolve api registration type UiPath.Core.Activities.ApiRegistration.PortableApiRegistration in assembly UiPath.System.Activities or UiPath.System.Activities.design
14:35:29.0705 => [ERROR] [UiPath.Studio.Project] [6] Failed to resolve api registration type UiPath.Testing.Activities.Portable.PortableRegisterWorkflowDesignApi in assembly UiPath.Testing.Activities or UiPath.Testing.Activities.design
14:35:29.3598 => [ERROR] [UiPath.Studio.Project] [1] Cannot locate resource ‘regexresources/themes/darkthemecolors.xaml’.

TJ_automates · January 18, 2023, 3:05pm

I resolved by ensuring al t he namespaces mentioned in the log were added. odd that it tested ok
