Got the below error while trying to open the organization.svc in browser. Although rest of the CRM was working properly.
Checked the event log and got this interesting error message over there.
Exception type: InsufficientMemoryException
Exception message: Memory gates checking failed because the free memory (208502784 bytes) is less than 5% of total memory. As a result, the service will not be available for incoming requests. To resolve this, either reduce the load on the machine or adjust the value of minFreeMemoryPercentageToActivateService on the serviceHostingEnvironment config element.
at System.ServiceModel.Activation.ServiceMemoryGates.Check(Int32 minFreeMemoryPercentage, Boolean throwOnLowMemory, UInt64& availableMemoryBytes)
at System.ServiceModel.ServiceHostingEnvironment.HostingManager.CheckMemoryCloseIdleServices(EventTraceActivity eventTraceActivity)
at System.ServiceModel.ServiceHostingEnvironment.HostingManager.EnsureServiceAvailable(String normalizedVirtualPath, EventTraceActivity eventTraceActivity)
As suggested by the error message, increasing the RAM resolved the issue.
We might receive the below error in CRM 2011 even though the user has the System Administrator Role assigned.
We need to check that the Access Mode for the system user is set to Read-Write and not Administrative.
In case if we receive the Insufficient Permission error
Go to Admin Section of your portal and select Assign User Licenses link in it
Assign License to the user
This will resolve the issue.
After downloading the SharePoint Designer 2013 installer on my lab machine and trying to run it I was getting the below error
Right clicking on it and selecting properties showed that it had the Digital Signatures tab missing in it.
Then downloaded the exe on my other machine, and it had the Digital Signatures tab.
Using this new exe on the lab machine I was able to install the Designer.
Hope it helps.
Similarly in Chrome and Firefox also we were getting the below error.
Finally we came to know it was because XPath is not supported in IE 10 and other browsers.

Hope it helps
