Can't reproduce.
Anyway, you should either write desolve(y'=x^2+exp(2*x)) or desolve(y'=x^2+exp(2*x),x,y)

It does not close with windows 7. Therefore it's some incompatibility with windows 10, and I can't do anything. Are you working with the 64 bits or 32 bits version? Try with the other version.

[]
Unable to isolate x in -exp(2*x)-x^2, switching to approx. solutions
Solving by bisection with change of variable x=tan(t) and t=-1.57..1.57. Try fsolve(equation,x=guess) for iterative solver or fsolve(equation,x=xmin..xmax) for bisection.
No solution found by bisection. Trying iterative method starting at 0
suggestion
In the title add please the current version, in order to see in the screenshots that are added to the documents, tutorials, the version in which works well,
Xcas New Interface, version stable (1.2.3, July 2017): 32 bits or 64 bits
