    How to Install Mathcad 15 on Windows 10

    Forgot to mention: I have owned a fully licensed node locked version of MC15 for several years. I was able to re-install MC15 after a clean reinstall of Windows 10 even though I am not on PTC support. This worked because I was installing MC15 on the same computer that it was on before. If I had...

    How to Install Mathcad 15 on Windows 10

    I installed Mathcad 15 m1010 in Windows 7 and later upgraded to Windows 10 and it ran fine under Windows 10 for a year or so. Unrelated to Mathcad, Windows 10 recently developed explorer issues, faulting every few minutes and restarting. Tried everything finally solving the issue by clean...

    Mathcad Prime 2.0 - Ready for "Prime-time" use yet?

    Just went back on maintenance (you have to pay for bug fixes) for MathCad 15 M010 and downlowded the free Prime 2.0, got the license file via email and copied/renamed it to c:\ptc\license.dat and mathcad 15 ran just fine, same as ever, not sure what bugs were fixed. Installed Prime 2.0, and...

    How to get Mathcad 6.0 on my new computer?

    You could also multi-boot. I run Windows 7 and Windows XP (each in it's own partition hidden from the other) using BootIt Bare Metal and for many tyears before that, BootIt NG. Both products allow you to multi-boot, create, resize, delete and format partions. There are videos on the Terabyte...

    Tip for Re-Installling MathCad 14 or 15?

    IRstuff: Good tip. What product do you use to wipe the registry? An ununstaller such as Revo or IObit (both portable versions) or a registry cleaner such as CCleaner?

    Tip for Re-Installling MathCad 14 or 15?

    I upgraded from Windows XP to Windows 7 and at the same time moved from MathCad 14 to MathCad 15 to ensure compatibility with Windows 7 and in the hope of a gaining few bug fixes, otherwise MCAD 15 seems to me to be identical to Mcad 14. I went on the Flexnet license server on the PTC website...

    How to get Mathcad 6.0 on my new computer?

    As IRStuff has suggested try downloading the free XPmode from Microsoft here http://www.microsoft.com/windows/virtual-pc/download.aspx There is a video that shows how to install and use it. I have been running Visio 4 (pre Microsoft, now 15 years old) and Quickbooks 2004 and several other...

    Phase-Ground VTs on Delta Transformer

    Folks: We have a project at substation where the transformer have delta secondary windings. The windings supply metal clad switchgear through U/G cable (PILC would be my guess by observation). The metal clad supplies a 13.8 kV distribution system. There is no sign of a grounding reactor at the...

    Model Number for CGE Distribution Transformer

    Gentlemen: We have a substation with uses six distribution transformers as bus potential VTs supplying protection, SCADA and revenue metering. The name plates have faded in with time and are nearly illegible. We cannot make out the model number but we can read some data stamped into the metal...

    BYM Bushing CT - Manufactured by Siemans or ABB?

    Folks: I have a set of bushing CTs that could be used for revenue metering if previously approved by the regulator. The name plate says they are type BYM part number 72-281-240-011 manufactured by Siemans Power T&D, inc. The regulator has posted approval for type BYM style 72281240011 (same...

    Factory tests on three winding transformer not self consistent

    I have a very complete set of factory test records for a three phase, three winding transformer, stepping tansmission voltage down to distribution voltage. There are four load-loss tests in the test pages, each recording impedance voltage and kW loss. The factory carried out the usual H-X...

    M14 Maintenance Contract + M15, when released.

    IRstuff: That's why I signed up - to get bug fixes for the M020 I am running now. Why the offer? Could it be that MathCad may have lost customers to Maple and MatLab when PTC started asking users to pay for bug fixes ... which used to be free before PTC took over. So I bet you are right: M035...

    M14 Maintenance Contract + M15, when released.

    Folks: I signed up for the offer. You get a MathCad14.0 CD by courier in a few days. And, I assume, as the offer says rights to MathCad 15.0 when it is released. You have to sign a waiver saying you will de-install 14.0 within 60 days after you get 15.0. Not sure why. And they want the...

    M020 release conditions

    Folks: M030 has been released. I cannot get it because my support has run out. PTC customer support says I can only get M030 if I buy a new maintanenace contract. I don't think I should have to pay for bug fixes. In the past patches were always available for free. I am angry about being...
