# GeoGebra-Windows-Portable-.zip for December

Roman Chijner shared this question 2 years ago

Hi, I have a program that worked at the end of last year, but it doesn't work now. I can't find the problem... Where can I find GeoGebra-Windows-Portable-.zip for December?

Hi,Thank you very much!!!

the ggb file is attached. Links : https://www.geogebra.org/m/d9ytv4wg https://www.geogebra.org/m/uuz6h7xq

The program works in GG6!!!, but very slowly. With the portable version of Geogebra 5 Classic under Windows 10 in the new versions I get errors: Command UnitVector(Object) Object-Number? Syntax: UnitVector(Object).

In the end-of-year versions, I was able to count for a large number of points. Now these files with the portable version are not opened.

It's running out of memory. You can try https://wiki.geogebra.org/e...

but you can make this command more efficient:

```If[e,Execute( Join(Sequence(Sequence("SetValue(A"+i+",(0,0)+R UnitVector( CopyFreeObject[Sum[Zip[UnitVector(A"+i+" -lP(r)),r,Sequence[n]\{"+i+"} ]]] ))",i,1,n),ii,1,i0) ) )]
```
At the moment it's recreating a lot of objects each time. Try eg

```B1=Sequence[n]\{1}
B2=Sequence[n]\{2}
etc
C1=Sum[Zip[UnitVector(A1 -lP(r)),r,B1 ]]
C2=Sum[Zip[UnitVector(A2 -lP(r)),r,B2 ]]
etc```

1. "It's running out of memory. You can try ..."

I am from the old "generation" and I can't do it... I use version 574 and there are no this problems!

2. Actual version -5.0.593.0-d:

I structured the calculation program: I entered B1... and C1...

Execute[Join[Sequence[{" B"+i+"= CopyFreeObject(Sequence[n]\{"+i+"}) ","C"+i+"= Sum[Zip[UnitVector(A"+i+" -lP(r)),r,B"+i+" ]]","SetConditionToShowObject[C"+i+",false] " },i,1,n] ]]

If[a,Execute( Join(Sequence(Sequence("SetValue(A"+i+",(0,0,0)+R UnitVector( CopyFreeObject[C"+i+" ] ))",i,1,n),ii,1,i0) ) )]

Counts 150 iterations, then the program crashes. See the attached file. You can periodically record the intermediate state and then continue counting!

Possibly memory overflow again ?! In version 574, there were no such cases (!!!). But the calculation was slowing down too, and I also continued to count after the Reopen.

How can you prevent the program from crashing.

Fixed in v603
