Unable to open >100MB images in fiji


I have >100MB size images and am trying to count the cells in each image.
Once I drag and drop one of the images, a dialogue box pops up, showing
the following:

"(Fiji Is Just) ImageJ 2.0.0-rc-69/1.52n; Java 1.8.0_172 [32-bit]; Windows 10 10.0; 726MB of 1198MB (60%)

I tried to do Edit-Options-Memory & Threads and increase the memory. But that didn’t work.
Any suggestions would be really appreciated.

Can you please try if setting the memory works as expected when using a 64-bit version of Fiji from here:


Thank you very much for the help. I tried downloading the 64 bit version and it works well.
