Resources for PTW Users
This page is designed to provide information for existing users of SKM Power*Tools for Windows (PTW) or other SKM software products. If you do not yet have PTW and would like to learn more, a full description is available here.
Note for all PTW users:
As part of the new SKM server system, all PTW users (new and existing) will have had an SKM account created automatically which is linked to their PTW license.
This happens regardless of whether you have previously registered on the SKM site or not.
Do not be tempted to create a new account on the SKM server as this will not be linked to your PTW license; you would not be able to download PTW updates using the new account.
See the "Downloads" section below for advice on how to log in to the SKM servers for the first time.

Downloads: Power*Tools for Windows
Full installation files and update patches are available. The process for downloading PTW, updates and other files has changed. Please follow the procedure below to access downloads:
- Click here to access the My SKM download page
- You will need to log in to the My SKM site. All customers with a valid update and maintenance agreement from CEE are automatically pre-registered with a My SKM account. The password for this site will be different to any passwords used in previous download sites (before April 2018).
- If you have not used My SKM before, click the "Forgot your password?" link and follow the on-screen instructions. Please note that your company's My SKM account will have been registered to the official contact for software upgrades. If this person has changed since the maintenance agreement was set up, or if a different email address is required, be sure to enter the new details in our Register PTW page.
- Once you have created a new password, keep it secure.
If you are experiencing difficulties with the new download site, please Contact Us for links to the latest downloads.
Do not use the update patches to update from V8.0 to V9.0. The update patches must only be used when updating from one revision of V9.0 to another revision of V9.
If you are updating from one revision to another, after making sure the software isn't already running, simply extract the files into the program directory. Some of these files are self-extracting ZIP files (.EXE), and some are standard ZIP files (.ZIP).

Downloads: Other Software
Full installation files can be downloaded from the My SKM servers; see the log-in instructions above. Please note that the "PTW Data Collection" and "PTW Viewer" programs are actually part of the main PTW program.
Therefore:
Therefore:
- Users of PTW Data Collection should download PTW version 8.0 or higher.
- PTW Viewer is available as part of V7.0, V8.0 and V9.0; if your project is being edited using one of the earlier versions, (for example PTW V7) and you wish to keep using V7 then users of PTW Viewer must download PTW version V7.

Training Courses
Are you a new PTW user or do you just want to brush up your skills? Maybe you have just purchased a new module and need to know how it works. CEE Relays can offer training courses tailored to your specific needs.
Courses are generally between one and four days in length and fall broadly into one of two categories:
An Introduction to PTW
Intended for novice users of PTW who want to start being productive as quickly as possible. Covers essential topics such as populating the Single-Line Diagram view, entering equipment data and running studies. Notify us in advance if your delegates have previous experience of similar programs or older versions of PTW so that we can adjust the course content accordingly. The exact course programme will vary depending on which PTW modules you have purchased.
Advanced Techniques
Intended for experienced users who want to get more out of PTW or find themselves modelling particularly complex or unusual projects. Notify us in advance if there are any specific topics you would like your course to cover.
We can run training courses either at your premises or at our head office in Slough. Durations depend largely on how many PTW modules you are using and how many delegates you wish to send. We recommend that all delegates are of roughly the same level of experience with PTW; it is inadvisable for novices and experienced users to attend the same course.
Please contact us if you would like to find out more.
