#15166 The error you refer to is not a compiling error, but an uploading one. Did you try just the compile option?

If that works, you do not have a problem with the IDE, or your system being a 32 bit one.

Your error is typically caused by the ESP not being in the flash mode (IO_0 not grounded), or the module/com port not defined properly in the IDE.
