Note: When troubleshooting, it may also be ideal to capture the UiExplorer verbose logs in DebugView. Remove all filters by going to Filters → Reset and search for OLEACC.dll OLEACC.dll however is a system dll, so in this case the path should be resolved via the registry.The solution here is to simply to delete the activity package and reinstall it. In this scenario the file was accidentally deleted. Click the UiEventHook.dll path and use Jump To (11).It appears UiEventHook.dll is not in the folder and so is OLEACC.dllĪs OLEACC.dll is a system library our dependency mechanism will resolve the path from the registry.Filter the whole log by Result NAME NOT FOUND and Show File System Activity (13).The first assumption would be a file is missing. Only system components use actual registry keys (like oleacc32.dll) and these need to be in the registry. nuget feed, so we rely on a manifest to find the specific libraries we use. ĭriver components are not registered because they're kept upto date constantly through the. UiExplorer is trying to find a specific component registered in the registry with the CLSID.The logs can get pretty large pretty fast so it is essential to work swiftly and try to close as much as the noise as possible during replication.Įxample Issue: When starting UiExplorer and indicating a specific element the following error appears, Here is possible to toggle filters to isolate just the target application. How to Interpret & Use Process Monitor Logs: The Procmon file can be analyzed ad-hoc by opening it up in Procmon. Show Profiling Events- Toggles On/Off the visualization of Process Profiling Activity.Show Process and Thread Activity - Toggles On/Off the visualization of Process and Thread Activity.Show Network Activity - Toggles On/Off the visualization of Network Activity.Show File System Activity - Toggles On/Off the visualization of System Activity.Show Registry Activity - Toggles On/Off the visualization of Registry Activity.Jump to object - browses for the object.įor example if selecting a registry event this will open Regedit to the exact registry key used.Find - can be used to search the process list columns.Event Properties - Access the properties of a highlighted event.One can use it to view how processes were spawned and killed in chronological order. Show Process Tree - Display the unfiltered process tree along with timelines.Include Process from Window - Automatically isolates and creates filters only for the targeted process.Similarly it one can highlight specific elements in the same manner as filtering. Highlight - Opens up the Highlight menu for the current highlights.For example to filter out all events from a PID 9925 one would click the value 9925 in the column PID and select Exclude '9925' These can be built either in the filters or by right clicking the column and element that need to be filtered in the list. Filter - Opens up the currently existing filters.Autoscroll - Stops the auto-scrolling of logs.How to Use Process Monitor Example of a captured log This process interaction can generate some of the issues below where Process Monitor can aid in the investigation: The missing / unregistered DLLs along with the file-path where the UiExplorer tries to locate them will be visible in Process MonitorĪt the same time various processes are created and terminated or interact with UiPath processes. In order to troubleshoot these issues the following information is necessary: Executing a workflow on a specific machine after a Windows Update throws unable to find selector errors.CLSID Registry errors when trying to inspect elements in specific applications, or execute workflows using selectors in those applications.In UiExplorer, selectors cannot be retrieved for some elements, or all elements.Missing proprietary DLLs, unregistered system DLLs or lack of access due to system restrictions can cause multiple issues with some of the symptoms below: In order to spy/inject data into different applications the driver component uses multiple Dynamic-link libraries (or DLL), both proprietary and belonging to the OS, which store the necessary code for multiple technologies. It captures events for processes and threads (where a process is started, a thread starts or exits, how processes are interacting with other processes, etc.) Introduction: Process Monitor is an advanced monitoring tool for Windows that shows real-time file system, Registry and process / thread activity. How to use Process Monitor( ProcMon) to troubleshoot issues related to UiPath Processes?
