Requirements and Troubleshooting is the latest model for running TempWorks Applications like Enterprise.

In order to use, you must have an updated Remote Desktop (RDP) client on a supported system, such as the following...

  • Windows XP  - Service Pack 3 with additional hot fixes (Upgrade is highly recommended)
  • Windows Vista - Service Pack 1 with additional updates (Upgrade is highly recommended)
  • Windows 7 - Service Pack 1 with additional updates (Upgrade recommended)
  • Windows 8 / 8.1 / 10 (built in support)
  • Mac OS X version 10.5.8 and later - with Microsoft Remote Desktop Connection Client (limited support)
Internet access is required and connectivity to IP address space on the appropriate protocols must not be restricted by your local network. 

Other common problems...
  1. Improper lmCompatibilityLevel causes failure to connect to remote apps on certain computers (found in some OEM Windows installations, notably Lenovo laptops) 
    1. See the "Improper ImCompatibilityLevel" section of this article for additional information. 
  2. Slow file transfer when uploading or saving documents over the drive shares to your local computer
    1. See the "slow document attachment and retrieval over remote app drive shares" section of this article for additional information. 

Windows XP

We strongly recommend you consider upgrading as Microsoft has dropped all support for Windows XP as of April 8, 2014.

Support may not be offered for all issues on Windows XP clients.
The following requirements must be met.
  • Service Pack 3 must be installed
  • The RDP 7 client update must be installed - RDP 7 client update for Windows XP SP3
  • Network Level Authentication (NLA) must be supported and enabled
  • Fix for drive redirection is recommended

Windows Vista

We strongly recommend you consider upgrading as Microsoft has dropped all support for Windows Vista as of April 11, 2017.

Support may not be offered for all issues on Windows Vista clients. 

Windows 7

We recommend you consider upgrading as Microsoft has dropped mainstream support for Windows 7 as of January 13, 2015

Windows 7 will have limited support with the following requirements. 

Windows 8+

Windows 8+ is supported with the following recommendations.

Mac OS X

Mac OS X 10.5.8 and later may function without official support.

It will require the Microsoft Remote Desktop Connection Client for Mac 

support for printing and file transfer may not be available. 

Remote App Network - Firewall Requirements

  • Must allow outbound connections on HTTP(80)/HTTPS(443) to
  • Must not Proxy this traffic
  • Remote App traffic should not cached or filtered. (deep HTTP packet inspection/filtering should be avoided)
  • If using outbound firewall rules, allow traffic on TCP/80 and TCP/443
  • If desired, you can only allow traffic to our hosting data center at IP

Improper ImCompatibilityLevel

Some computer vendors and other 3rd party software may set an lmCompatibilityLevel that is outdated and incompatible with TempWorks RemoteApp and other secure network services.

This has been experience most prevelantly with some new Windows 8.1 laptops from Lenovo, but could affect other systems as well. 

The setting can be found in the Windows Registry by using RegEdit, great care must be taken in modifying the registry, consult your IT provider. 


The value needs to be 3 or higher. (Probably best to remove the LmCompatibilityLevel key altogether, don't break the registry!)

On a Windows 8+ computer you can remove the LmCompatibilityLevel key and the default will work.

The following article describes navigating to and modifying the LmCompatibilityLevel key.

Slow Document Attachment and Retrieval Over Remote App Drive Shares

Firstly, if you are using Windows XP ensure the latest RDP client and hot fixes are installed which can contribute to slow file transfer performance. 

Check your network connection quality to understand your effective throughput. You can do this using TempWorks network connection Quality test. Understand that this test will give different results than popular sites like, the reason for this is that popular sites seek to measure maximum speed of your connection but do not make any attempt to test the quality of the connection which can reduce effective throughput. Take a screenshot of the results or record the "test ID" for later reference by TempWorks Support team.

Another test you can perform is to estimate the effective throughput of the remote app drive share by attaching and then downloading one of the following test files as a document on a test customer/employee record. 





The following table can be used to estimate the effective throughput of your connection based on the time it takes to attach (upload) or save (download) the test file in TempWorks.

Tiny file: 1 MBSmall file: 3 MBMedium file: 12 MB
30 second = 1/4 Mbps25 second = 1 Mbps45 seconds = 2 Mbps
15 seconds = 1/2 Mbps12 second = 2 Mbps30 seconds = 3 Mbps
8 seconds = 1 Mbps8 second = 3 Mbps18 seconds = 5 Mbps
4 seconds = 2 Mbps5 second = 5 Mbps9 seconds = 10 Mbps
< 1 seconds = >8 Mbps< 3 second = >10 Mbps<4 seconds = >20 Mbps
