I've noticed for some reason it will sometimes install things in a folder called BikeCAD Pro 15.0 but will put it in BikeCAD Pro 16.0 after an uninstall and a reinstall. I'm sorry I cannot explain why it would do this.

I get the error mentioned only when trying to install the 64bit. 32bit install works as expected.


Stay safe and Keep up the great work Brent!!

Thanks for the suggestion Eric. Using the 32 bit version is another option. However, for anyone looking to use the 64 bit version, it appears that there can be complications when earlier versions of BikeCAD are already installed. However, uninstalling and installing once more does seem to work as well.

Bike cad 16.0 will not save drawing changes. It opens the save drawing window but once closed and opened again the drawing appears with out the changes made prior to save. Any ideas.



This is the first time anyone has reported this. I wonder if there is something about the particular design you are trying to save. Could you send me the BCAD file in question and let me know what kind of change you are attempting to make?

The only other thing I can think to mention is that double clicking on a BCAD file will not open that particular design. You have to either choose File >> Open design from BCAD file or drag and drop the file into the main BikeCAD window.

As far as I am aware, everyone impacted by this has been able to resolve the issue by uninstalling older versions first. Another option would be to run the 32 bit version. Let me know how you get along.

Hi Brent, BikeCAD 16.0 v1.0 on MacOS 10.15.7. A small nuisance: app window display prefs, such as window position and size, are no longer saved after upgrading from 15.0.



Thanks for letting me know about this. I have not been able to replicate this issue at my end. There were not meant to be any changes related to this in moving to version 16.0. Your dialog box dimensions and locations are stored in a file called: dialogs1.xml. This file should be found in the folder called: BikeCAD_16.0_configuration. As this file does not seem to be doing anything for you, you could delete it. BikeCAD will create another file next time you open and close the program. I wonder if, since your dialog box information is not being stored, there might be any other things that are not being stored. For example, are you able to go to View >> Customize >> Save current bike as default template? Doing that should save the model that you are currently viewing so that it will appear as the default design when you launch BikeCAD. I wonder if BikeCAD might not have permission to write to your BikeCAD_16.0_configuration directory. This is why I'm curious to know what other customization options can be implemented.

Hi Brent. dialogs1.xml is nowhere to be found in my 16.0 install. I see it (and _2 & _3.xml as well) in my 15.0 install which is still on the same HDD. 

I'm able to save current display as default, as you describe, and have it take effect next restart.

Sounds like a 16.0 reinstall is in order, or would you like me to check anything else for you?

This is strange. The fact that you can save your current bike as the default template suggests that BikeCAD is able to write files to your BikeCAD_16.0_configuration directory. Therefore, it should in theory also be able to write the dialogs1.xml file. I might try copying your dialogs1.xml file from your BikeCAD_15.0_configuration directory into your BikeCAD_16.0_configuration directory. At the very least, this should display all the dialog boxes in the same position and size as they were in version 15.0. If BikeCAD still can't update the dialogs1.xml file with your new dialog box positions, then this may not be a good long term solution, but it would be interesting to see if it at least applies the settings from version 15.

Copying 15.0's dialogs1.xml does apply my old window size/location to 16.0. However, changing window size location in 16.0 then restarting does not have any effect.

I'm still able to save a default template in view/customize.

Thanks for letting me know. I'd be very curious to know if anyone else can replicate this behaviour. I hope I can get this resolved for you in the next update.

Hi Brent,

Ever since I installed ver.16 on my MacBook Pro  BigSur 11.0.1 I cannot use the BikeCad software.

It opens fine but as soon as I try to change anything on a frame the option window opens in full screen and the app doesn't respond anymore.

I have to force quit.

I have uninstalled, empty recylcle bin and re-installed few times without success.

Any hints or advice to make it work?

I believe you may be the sixth person reporting issues with Mac OS 11.0.1. Many of these users have also had trouble with other software since upgrading to this version of Big Sur. As far as I can tell, the issue is beyond my control. However, I believe the problem might have been resolved with the latest Mac OS which as of December 14, 2020 is 11.1.

I'd be curious to hear from other Mac users about their experiences.

Thank you for your reply.

I have updated to Mac OS 11.1 deleted BikeCad and re-installed it but unfortunately it still freezes as soon as I try to use it.

Any suggestion at this stage? 


I'm sorry to hear you went through all that and still have no luck.

First thing to be aware of is that your license of BikeCAD entitles you to install the program on up to three of your own computers, so if you have access to another computer, that could be one solution.

While I assume the issue is related to these latest Mac updates that will hopefully be resolved in a future update, it is strange, because I know of some other users that are running BikeCAD on Mac OS 11.1 without issue. You said you uninstalled BikeCAD before re-installing it. When running BikeCAD for the first time, a directory called BikeCAD_16.0_configuration will be created to store customization data. When you uninstall BikeCAD, this directory doesn't necessarily get deleted as well. In case the problem has to do with some sort of corrupt configuration file, it could be worth deleting this directory. I would not worry about uninstalling BikeCAD again. You've already tried that, and this is a separate possible cause. If you delete the BikeCAD_16.0_configuration folder and then try to launch BikeCAD, BikeCAD should look for the configuration directory. If it does not find it, it should extract a new folder. It would be nice if once the new folder is extracted BikeCAD works as normal.

A final possibliity could be to install the Java Runtime Environment (JRE) on your machine and then run the Linux version of BikeCAD which should run on any computer that is running the Java JRE.

I'm sorry I have no definite solution for you, but I hope this can get resolved soon.
